Al Cooper b0c0b66c0b phy: usb: Add support for wake and USB low power mode for 7211 S2/S5 
Add support for 7211 USB wake. Disable all possible 7211 USB logic
for S2/S5 if USB wake is not enabled.

On the 7211, the XHCI wake signal was not connected properly and
only goes to the USB1_USB1_CTRL_TP_DIAG1 diagonstic register.
The workaround is to have VPU code running that polls for the
proper bit in the DIAG register and to wake the system when
the bit is asserted.

Al Cooper 9d5f51dcdb phy: usb: Add support for new Synopsys USB controller on the 7211b0 
The 7211b0 has added the STB XHCI Synopsys controller and it
will be used instead of the RPi based DWC USB controller. The new
Synopsys XHCI controller core is the same one that is used on the
7216, but because of the way the STB USB PHY is used on both the A0
and B0, some of the PHY control is different.

Al Cooper 94583a4104 phy: usb: Restructure in preparation for adding 7216 USB support 
The driver is being restructured in preparation for adding support
for the new Synopsys USB conroller on the 7216. Since all the bugs
and work-arounds in previous STB chips are supposed to be fixed,
most of the code in phy-brcm-usb-init.c is not needed. Instead of
adding more complexity to the already complicated phy-brcm-usb-init.c
module, the driver will be restructured to use a vector table to
dispatch into different C modules for the different controllers.

There was also some general cleanup done including some ipp setup
code that was incorrect.

Al Cooper f1c0db40a3 phy: usb: Add "wake on" functionality 
Add the ability to handle USB wake events from USB devices when
in S2 mode. Typically there is some additional configuration
needed to tell the USB device to generate the wake event when
suspended but this varies with the different USB device classes.
For example, on USB Ethernet dongles, ethtool should be used to
enable the magic packet wake functionality in the dongle.
NOTE:  This requires that the "power/wakeup" sysfs entry for
the USB device generating the wakeup be set to "enabled".

This functionality requires a special hardware sideband path that
will trigger the AON_PM_L2 interrupt needed to wake the system from
S2 even though the USB host controllers are in IDDQ (low power state)
and most USB related clocks are shut off. For the sideband signaling
to work we need to leave the usbx_freerun clock running, but this
clock consumes very little power by design. There's a bug in the
XHCI wake hardware so only EHCI/OHCI wake is currently supported.

Al Cooper 6597af4e48 phy: usb: Put USB phys into IDDQ on suspend to save power in S2 mode 
Currently the Phy driver will put the USB phys into the max
power saving mode (IDDQ) when there is no corresponding XHCI, EHCI
or OHCI client (through rmmod, unbind or if the driver is not
builtin). This change will also put the Phys into IDDQ mode
on suspend so that S2 will get the additional power savings.

Al Cooper dc9aa43c43 phy: usb: EHCI DMA may lose a burst of DMA data for 7255xA0 family 
When the EHCI controller received a 512 byte USB packet that
had to be broken into 2 256 byte bursts across the SCB bus AND
there was a following 512 byte USB packet, the second burst of
data from the first packet was sometimes being lost. If the
burst size was changed to 128 bytes via the EBR_SCB_SIZE field
in the USB_CTRL_EBRIDGE register we'd see the 4th 128 byte burst
of the first packet being lost. This problem became much worse
if other threads were running that accessed memory, like a memcpy
test. Setting the EBR_SCB_SIZE to 512, which prevents breaking
the EHCI USB packet (max size of 512 bytes) into bursts, fixed
the problem.

Al Cooper 0aa0c12262 phy: phy-brcm-usb-init: DRD mode can cause crash on startup 
This is caused by a bug in the BDC core. When the BDC core comes
out of reset and it's not selected, it gets a backup clock. When
the BDC core is selected, it get's the main clock. If HOST mode
is then selected the BDC core has the main clock shut off but
the backup clock is not restored.

The failure scenario and cause are as follows:
- DRD mode is active
- Device mode is selected first in bootloader
- When host mode is now selected, the clock to the BDC is cut off.
- BDC registers are inaccessible and therefore the BDC driver
  crashes upon Linux boot.

The fix is to have the phy driver always force a BDC reset on
startup.

Set PHY3_IDDQ_OVERRIDE in the xhci uninit routine. This will save
additional power when the XHCI driver is not enabled.

Enable the the Low Speed Keep Alive signal on the 7271b0 by setting
the LS_KEEP_ALIVE bit in the USB CTRL OBRIDGE register otherwise
some Dell Low Speed keyboards fail.

Also do a little cleanup of the EBRIDGE ESTOP_SCB_REQ bit. Since
this is only used on one platform, remove it from the platform
tables and just use "if (family == ").
