So we can add i.MX8M support without introducing name clashes.

i.MX8MQ and i.MX8MM share same gpc module with i.MX7D, they
can reuse gpcv2 pgc driver for power domain control, this
patch renames all functions and structure definitions started
with "imx7" to "imx", and use .data in imx_gpcv2_dt_ids[] to
pass platform specific power domain data for power domain
driver, thus make gpcv2 pgc driver more generic for i.MX
platforms.

gpcv2 driver is NOT just used on i.MX7D which has Cortex-A7
cores, but also on i.MX8MQ/i.MX8MM platforms which use Cortex-A53
cores, so let's use A_CORE instread of A7 to avoid confusion.

imx6_pm_domain_power_off() reads iso and iso2sw from GPC_PGC_PUPSCR_OFFS
which stores the power up delays.
So use GPC_PGC_PDNSCR_OFFS for the correct delays.

Some of the larger changes this merge window:
- Removal of drivers for Exynos5440, a Samsung SoC that never saw
widespread use.
- Uniphier support for USB3 and SPI reset handling
- Syste control and SRAM drivers and bindings for Allwinner platforms
- Qualcomm AOSS (Always-on subsystem) reset controller drivers
- Raspberry Pi hwmon driver for voltage
- Mediatek pwrap (pmic) support for MT6797 SoC

- Handle i.MX6SL chip errata ERR006287 in the safest possible way by
keeping the DISP domain always-on, because Upon resuming from power
gating, the modules in the display power domain (eLCDIF, EPDC, PXP
and SPDC) might fail to perform register reads correctly.
- Use GENPD_FLAG_ALWAYS_ON flag for i.MX6QP PU ERR009619 handling.
It is functionally identical to the exsiting implementation but
simpler and slightly faster.
