Add Serial Download Protocol support as it is a useful method to
load flash.bin to RAM and run it via 'uuu'.
With this patch, it is possible to start both U-Boot SPL and U-Boot
proper using the following 'uuu'command:
$ uuu -brun spl flash.bin
Based on a patch from Marek Vasut for the imx8mm-mx8menlo board.
Also, to fit the SPL binary into the internal RAM, select CONFIG_LTO
to reduce its size.

Mark pinctrl_wdog as u-boot,dm-spl to clean up board code,
The set_wdog_reset() function is not necessary as this is handled by
the imx_watchdog.c driver due to the 'fsl,ext-reset-output' property
being set.

With the move to using binman to generate SPL aka u-boot-spl-ddr.bin and
U-Boot proper aka u-boot.itb every board now covers such configuration
in its own U-Boot specific device tree include. Move the comon part of
that configuration to the common imx8mm-u-boot.dtsi include file.

After the conversion to binman in commit 8996e6b7c6 ("imx8mm_evk: switch
to use binman to pack images"), it is necessary to flash both flash.bin and
u-boot.itb to get a bootable system. Prior to this commit, only flash.bin
was needed.
Such new requirement breaks existing distro mechanisms to generate the
final binary because the extra u-boot.itb is now required.
Generate a final flash.bin that can be used again as a single
bootable binary to keep the original behavior.
After this change the SPL binary is called spl.bin, which is a more
descriptive name for its purpose, and can still be used standalone
(for example, for secure boot purposes).
Also update imx8mm_evk.rst to remove the u-boot.itb copy step.

Some board like imx8mm-evkb, IO voltage switch from 3.3v to 1.8v need
around 18ms, common code only delay 10ms, so need to delay extra 8ms.
Otherwise voltage switch will timeout when wait for data0 line.
This IO voltage switch time depends on board design, depend on the
PMIC and capacitance. imx8mm-evkb board use PCA9450(PMIC) and 10uF
capacitance.

Add DEK blob encapsulation support for IMX8M through "dek_blob" command.
On ARMv8, u-boot runs in non-secure, thus cannot encapsulate a DEK blob
for encrypted boot.
The DEK blob is encapsulated by OP-TEE through a trusted application call.
U-boot sends and receives the DEK and the DEK blob binaries through OP-TEE
dynamic shared memory.
To enable the DEK blob encapsulation, add to the defconfig:
CONFIG_SECURE_BOOT=y
CONFIG_FAT_WRITE=y
CONFIG_CMD_DEKBLOB=y

Some SD Card controller and power circuitry has increased capacitance,
which keeps the internal logic remains powered after regulator is switch
off. This is generally the case when card is switched to SD104 mode,
where a power cycle should be performed. In case if the card internal
logic remains powered, it causes a subsequent failure of mode
transition, effectively leading to failed enumeration.
Introduce a delay of 20 msec in order to provide a possibility for
internal card circuitry to drain voltages and perform a power cycle
correctly.
Similar fix is done in commit c49d0ac38a ("ARM: dts: rmobile: Increase
off-on delay on the SD Vcc regulator") targeted Renesas SOCs.

Board files should not re-implement do_reset() to work around this
function not being defined in for specific configurations. Rather,
the fix is to compile in drivers which implement this properly.
This patch enables sysreset and watchdog drivers in SPL and ties
them together to implement the same as the do_reset() hack in the
board file, except correctly in the DM/DT framework.
