74f88b7221 ARM: imx: imx8m: Fix board_get_usable_ram_top()
The 4 GiB boundary is at 0xffffffff+1 , not at 0x80000000, fix this.

The PHYS_SDRAM of i.MX8M is at 0x40000000 , so to restrict ram_top
below 4 GiB, the ram_top has to be set to 0xffffffff as it is not
an offset from the start of PHYS_SDRAM, but rather a physical address
marking the topmost allowed DRAM address.

6f6e069ca3 pci: imx: use vpcie-supply if defined by device-tree
If vpcie-supply is defined by device-tree use that if
CONFIG_PCIE_IMX_POWER_GPIO is not defined.

Note that after this the following boards which define
CONFIG_PCIE_IMX_POWER_GPIO in their board header file as well as their
device-tree should be able to remove CONFIG_PCIE_IMX_PERST_GPIO without
consequence:
 - mx6sabresd
 - mx6sxsabresd
 - novena

Note that the ge_bx50v3 board uses CONFIG_PCIE_IMX_POWER_GPIO and does
not have vpcie-supply defined in it's pcie node in the dt thus removing
CONFIG_PCIE_IMX_POWER_GPIO globally can't be done until that board adds
vpcie-supply.

 - move eeprom functions into eeprom file and elimate GSC_I2C_BUS
 - eliminate some redundant EEPROM reads (the EEPROM must be read in
   SPL before relocation, in SPL after relocation, and in U-Boot init.
   All subsequent uses can use the global structure)
 - remove unnecessary header files and alphabatize includes

Implement power_domain_get_by_name() convenience function which parses
DT property 'power-domain-names' and looks up power domain by matching
name.

4eb82c2e56 imx: power-domain: Get rid of SMCCC dependency
This driver is the only SMCCC dependency in iMX8M U-Boot port. Rework
the driver based on Linux GPCv2 driver to directly control the GPCv2
block instead of using SMCCC calls. This way, U-Boot can operate the
i.MX8M power domains without depending on anything else.

This is losely based on Linux GPCv2 driver. The GPU, VPU, MIPI power
domains are not supported to save space, since they are not useful in
the bootloader. The only domains kept are ones for HSIO, PCIe, USB.

19842b6a20 imx: power-domain: Inline arch-imx8m/power-domain.h
The arch/arm/include/asm/arch-imx8m/power-domain.h is not included
anywhere except in drivers/power/domain/imx8m-power-domain.c, just
inline the content and drop the header. No functional change.

8741d92756 imx: power-domain: Descend into pgc subnode if present
In case the power domain node structure is gpc@303a0000/pgc/power-domain@N,
do not bind power domain driver to the 'pgc' node, but rather descend into
it and only bind power domain drivers to power-domain@N subnodes. This way
we do not waste one useless driver instance associated with 'pgc' node.
