- 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
i.mx8qxp-mek# cat /sys/devices/soc0/revision

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 GPCv2 on the Freescale i.MX8MQ SoC works in the same way as the
GPCv2 on the i.MX7, but only controls more power domains with a
different mapping.

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.
