soc: imx: Add SoC device register for i.MX9

i.MX9 SoCs have SoC ID, SoC revision number and chip unique identifier
which are provided by the corresponding ARM trusted firmware API. This
patch intends to use SMC call to obtain these information and then
register i.MX9 SoC as a device.

soc: imx: add i.MX8M blk-ctrl driver

This adds a driver for the blk-ctrl blocks found in the i.MX8M* line of
SoCs. The blk-ctrl is a top-level peripheral located in the various *MIX
power domains and interacts with the GPC power controller to provide the
peripherals in the power domain access to the NoC and ensures that those
peripherals are properly reset when their respective power domain is
brought back to life.

Software needs to do different things to make the bus handshake happen
after the GPC *MIX domain is powered up and before it is powered down.
As the requirements are quite different between the various blk-ctrls
there is a callback function provided to hook in the proper sequence.

The peripheral domains are quite uniform, they handle the soft clock
enables and resets in the blk-ctrl address space and sequencing with the
upstream GPC power domains.

firmware: imx: Move i.MX SCU soc driver into imx firmware folder

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.

soc: imx: move PGC handling to a new GPC driver

This is an almost complete re-write of the previous GPC power gating control
code found in the IMX architecture code. It supports both the old and the new
DT binding, allowing more domains to be added later and generally makes the
driver easier to extend, while keeping compatibility with existing DTBs.

As the result, all functionality regarding the power gating controller
gets removed from the IMX architecture GPC driver. It keeps only the
IRQ controller code in the architecture, as this is closely coupled to
the CPU idle implementation.
