changes since v2:
- drop some superseeded patches
- reduce the amount of commits
- modernize the 8992 dts
- add libra and talkman DTSes
- do some housekeeping and fix minor issues
Tested on Libra and Talkman. Bullhead *shouldn't* break.
Depends on my 8994 patchset [1] (because of compatibles
and 8992-related SMD RPM patches) and my RPMCC patch [2].

2.27.0
This commit ensures the correct IRQ type is set
and disables the device by default.
The mmc-hs400-1_8v property is also moved to
Bullhead as it might not be present on all boards.
The node has been renamed to sdhci@ instead of mmc@
and the phandle was changed to sdhc_1 to comply with
the newer DTS style.

Add support for I2C to enable support for peripherals
such as touchscreens or sensors. Also add BLSP_UART2 interface.
Please note that the naming scheme follows downstream and as
abominable as it is, that's what we get.

2.27.0
Add device tree support for the Microsoft Lumia 950 smartphone.
It is based on msm8992 and supports booting Linux via a custom
EDK2 port.
Currently it supports:
* Screen console via EFIFB
* Booting via EFI_STUB
* SDHCI
* I2C
* PSCI core bringup
Please note that there is an implementation of EL2 startup
on this board, but it requires the user to resign from
PSCI and use spin-table instead. This revision sticks with
PSCI.

Add the PMU so we can get proper perf event support on this SoC.

2.27.0
This pinout is common for every 8992-based device and
should therefore reside in the SoC device tree.
Also convert addresses into phandles.

2.27.0
Add the property required for the bootloader to select
the correct device tree blob. It has been removed from
the SoC device tree as it should be set on a per-device
basis.
