We are currently using SC_R_LAST as a marker for imx8 power domain tree
nodes without a resource attached. This value is compiled into dtb as
part of the linux build and used by uboot.
The SC_R_LAST constant changes frequently as SCFW resources are added
(by design) and every time we need to update linux and uboot headers
together or boot can fail.
Fix this by replacing SC_R_LAST usage with a new constant SC_R_NONE
defined to be 0xFFF0.

The CONFIG_SPL_FORCE_MMC_BOOT config flag is not needed as its behavior
is the correct one in all cases; using spl_boot_device() instead of the
boot_device parameter will lead to inconsistency issues, for example,
when a board_boot_order() is defined. In fact, this is the reason the
parameter was introduced in the first place, in commit 2b1cdafa9f
("common: Pass the boot device into spl_boot_mode()").
This reverts commit 772b55723b.

Boards may extend or re-define the boot list in their board_boot_order()
function by modifying spl_boot_list. E.g. a board might boot SPL from a
slow SPI NOR flash and then load the U-Boot from an eMMC or SD-card.
Or it might use additional MMC boot device in spl_boot_list for cases
when the image in SPI NOR flash is not found, so it could fall back to
eMMC, SD-card or another boot device.
Getting the MMC boot mode in spl_mmc will fail when we are trying to
boot from an MMC device in the spl_boot_list and the original board
boot mode (as returned by spl_boot_device()) is not an MMC boot mode.
Fix it by checking the asked MMC boot device from the spl_mmc_boot_mode()
argument.

On SPL enabled systems, the current s_init code (wdog, clock and ldo
init) is executed twice (by SPL and u-boot). This is not necessary and
might lead to boot issues (ie, starting PMC1 when it is already running).

At present panic() is in the vsprintf.h header file. That does not seem
like an obvious choice for hang(), even though it relates to panic(). So
let's put hang() in its own header.

The drivers/clk/imx/*.c are used for CLK dm case, the
clock_imx8mm.c is used for non CLK dm case, let's split
it. Sometimes it is hard to enable CLK dm in SPL stage,
considering code size, malloc size requirement, the splittion
will make it easy to use non CLK dm in SPL stage.

Currently imx-specific bootaux command doesn't support ELF format
firmware for Cortex-M4 core.
This patches introduces a PoC implementation of handling elf firmware
(load_elf_image_phdr() was copy-pasted from elf.c just for PoC).
ELF64 binaries isn't supported yet.
This has the advantage that the user does not need to know to which
address the binary has been linked to. However, in order to handle
and load the elf sections to the right address, we need to translate the
Cortex-M4 core memory addresses to primary/host CPU memory
addresses (Cortex A7/A9 cores).
This allows to boot firmwares from any location with just using
bootaux, e.g.:
> tftp ${loadaddr} hello_world.elf && bootaux ${loadaddr}
Similar translation table can be found in the Linux remoteproc
driver [1].

The %08X format returns just zeroes with tiny printf, which is
horribly confusing, especially when debugging DRAM calibration
problems. Change the format to %08x (with lowercase x), which
behaves correctly with either implementation of printf in SPL.
