Add PM suspend callbacks to the msm core driver that select the
sleep and default pinctrl states. Then wire those callbacks up
in the sdm845 driver, for those boards that may have GPIO hogs
that need to change state during suspend.

The 'tiles' array is initialized to a constant pointers to constant
strings, but the declaration is only half as constant:
drivers/pinctrl/qcom/pinctrl-qcs404.c:1660:11: error: initialization discards 'const' qualifier from pointer target type [-Werror=discarded-qualifiers]
drivers/pinctrl/qcom/pinctrl-sdm660.c:1417:11: error: initialization discards 'const' qualifier from pointer target type [-Werror=discarded-qualifiers]
Let's make it more constant.

On some new platforms the tiles have been placed too far apart to be
covered in a single ioremap. Turn "regs" into an array of base addresses
and make the pingroup carry the information about which tile the pin
resides in.
For existing platforms we map the first entry regs and the existing
pingroups will all use tile 0, meaning that there's no functional
change.

GPIO_PULL bits configurations in TLMM_GPIO_CFG register
differs for IPQ40xx from rest of the other qcom SoCs.
As it does not support the keeper state and therefore can't
support bias-bus-hold property.
This patch adds a pull_no_keeper setting which configures the
msm_gpio_pull bits for ipq40xx. This is required to fix the
proper configurations of gpio-pull bits for nand pins mux.
IPQ40xx SoC:
2'b10: Internal pull up enable.
2'b11: Unsupport
For other SoC's:
2'b10: Keeper
2'b11: Pull-Up
Note: Due to pull_no_keeper length, all kerneldoc entries
in the msm_pinctrl_soc_data struct had to be realigned.

On newer TLMM hardware blocks the registers are spread and
we need an offsets upper than 16 bits to address them. Increase
the register offset variables to 32 bits size.

Currently the value used to specify that interrupts from the gpio should
be routed to the application processor is hardcoded for all Qualcomm SoCs.
But the new APQ8084 SoC uses a different value. To resolve this, we make
this value configurable for each SoC. For all existing SoCs we continue
to use the current value, and only for APQ8084 we use the new value.

We have four Qualcomm-related pin control drivers, and now there
are drivers coming in for the PMICs on these systems, so let's
create a qcom subdirectory to hold all the Qualcomm stuff.
