9b0bb07328 soc: imx: Break dependency on SOC_IMX8MQ for GPCv2
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.

685efffe37 soc: imx: gpcv2: add support for i.MX8MQ SoC
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.

e23c7f7d57 soc: imx: add PM dependency for IMX7_PM_DOMAINS
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.

03aa12629f soc: imx: Add GPCv2 power gating driver
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.
