The Kconfig options belongs closer to the corresponding implementations,
hence let's move them from the soc- and firmware subsystem to the pmdomain
subsystem.

Currently the dependencies of the blk-ctrl drivers are not fully
described in Kconfig, which can trip over the compile tests on
platforms where those drivers are not usually enabled. Add a
non user-selectable symbol to be describe those dependencies.

Selecting ARM_GIC_V3 on non-CP15 processors leads to build failures
like
arch/arm/include/asm/arch_gicv3.h: In function 'write_ICC_AP1R3_EL1':

Add a dependency to only enable the gic driver when building for

processor that is actually in this chip.

Select ARM_GIC_V3, then it is able to use gic v3 driver in aarch32
mode linux on aarch64 hardware. For aarch64 mode, it not hurts
to select ARM_GIC_V3.

The i.MX SCU soc driver depends on SCU firmware driver, so it has to
use platform driver model for proper defer probe operation, since
it has no device binding in DT file, a simple platform device is
created together inside the platform driver. To make it more clean,
we can just move the entire SCU soc driver into imx firmware folder
and initialized by i.MX SCU firmware driver.

Compile-testing the driver can result in a link failure
when CONFIG_SOC_BUS is disabled:

The soc-imx8.c driver is actually for i.MX8M family, so rename it
to soc-imx8m.c.
Use CONFIG_SOC_IMX8M as build gate, not CONFIG_ARCH_MXC, to control
whether build this driver, also make it possible for compile test.
Default set it to y for ARCH_MXC && ARM64

i.MX driver changes for 5.3:
- Add i.MX SCU based SoC bus driver for i.MX8QXP SoC support, which
talks to SCU firmware for getting SoC ID and revision.
- Update soc-imx8 bus driver to read imx8mm soc revision from anatop.
- Add i.MX8MN SoC bus support into soc-imx8 driver.
- Various small improvements on soc-imx8 bus driver.

Add i.MX SCU SoC info driver to support i.MX8QXP SoC, introduce
driver dependency into Kconfig as CONFIG_IMX_SCU must be
selected to support i.MX SCU SoC driver, also need to use
platform driver model to make sure IMX_SCU driver is probed
before i.MX SCU SoC driver.
With this patch, SoC info can be read from sysfs:
i.mx8qxp-mek# cat /sys/devices/soc0/family
Freescale i.MX
i.mx8qxp-mek# cat /sys/devices/soc0/soc_id
0x2
i.mx8qxp-mek# cat /sys/devices/soc0/machine
Freescale i.MX8QXP MEK

Since this is going to be used on more SoCs than just i.MX8MQ, make
the dependency here more generic by using ARCH_MXC instead.
Also remove the SOC_IMX7D since it is also included by the ARCH_MXC.

The new pm domain driver causes a build failure when CONFIG_PM
is not set:
warning: (IMX7_PM_DOMAINS) selects PM_GENERIC_DOMAINS which has unmet direct dependencies (PM)
drivers/base/power/domain_governor.c: In function 'default_suspend_ok':
drivers/base/power/domain_governor.c:75:17: error: 'struct dev_pm_info' has no member named 'ignore_children'
This adds a dependency to ensure that we don't attempt to build the
driver without CONFIG_PM.

Add code allowing for control of various power domains managed by GPCv2
IP block found in i.MX7 series of SoCs. Power domains covered by this
patch are:
- PCIE PHY
- MIPI PHY
- USB HSIC PHY
- USB OTG1/2 PHY
Support for any other power domain controlled by GPC is not present, and
can be added at some later point.
Testing of this code was done against a PCIe driver.
