arm: psci: Fix RESET2 hook
The RESET2 hook is a PSCI v1.1 functionality, rename the macro accordinly.
Add missing handler for the RESET2 hook, so it can be implemented by U-Boot.
They need to be kept so that the mmc cards are in the right order.
Without the aliases, u-boot reports:
MMC: FSL_SDHC: 2, FSL_SDHC: 3
With the aliases, u-boot reports:
MMC: FSL_SDHC: 0, FSL_SDHC: 1
The upstream linux device tree does not contain the same aliases than
u-boot (It keeps the devices order with /dev/mmcblk2 and /dev/mmcblk3).
Because this board has been using different aliases in u-boot
and linux, a imx6q-sabrelite-u-boot.dtsi file is added to be
automatically included in imx6q-sabrelite.dts.
This way, linux and u-boot each keep their own aliases and there
is no breakage on current installations.
This should never be done for new boards as we want to keep linux and
u-boot with the same aliases as much as possible.
This patch is only necessary to avoid breaking existing setups.
