OMAP4/5 has been (ab)using the gic_arch_extn to provide
wakeup from suspend, and it makes a lot of sense to convert
this code to use stacked domains instead.
This patch does just this, updating the DT files to actually
reflect what the HW provides.
BIG FAT WARNING: because the DTs were so far lying by not
exposing the WUGEN HW block, kernels with this patch applied
won't have any suspend-resume facility when booted with old DTs,
and old kernels with updated DTs won't even boot.
On a platform with this patch applied, the system looks like
this:

As usual, this is the largest branch, though this time a little under
half of the total changes with 307 individual non-merge changesets.
The largest changes are the addition of new machines, in particular
the Tegra based Chromebook, the Renesas r8a7794 SoC, and DT support
for the old i.MX1 platform.
Other changes include
- at91: various sam9 and sama5 updates
- exynos: much extended Peach Pi/Pit (Chromebook 2) support
- keystone: new peripherals
- meson: added DT for meson6 SoC
- mvebu: new device support for Armada 370/375
- qcom: improved support for IPQ8064 and MSM8x60
- rockchip: much improved support for rk3288
- shmobile: lots of updates all over the place
- sunxi: dts license change

LDO8 regulator is used for act led and serial cosole power supply.
Its DT status is declared as "disabled", however the serial console was
functional until Commit 318dbb02b ("regulator: palmas: Fix SMPS
enable/disable/is_enabled") wich properly turns off LDO8 on boot.

The OMAP4/5 TRMs primarily list address offsets from the padconf
physical address (which is not driver base address) and not
always the absolute physical address for padconf registers like
some other OMAP TRMs. So create a new macro to use this offset
and to avoid confusion between different OMAP parts.
For more information, see the tables in TRM for named something like
"Device Core Control Module Pad Configuration Register Fields"
and "Device Wake-Up Control Module Pad Configuration Register Fields"
Note that we now also have to update cm-t54 for the fixed up
offsets.
