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.

It turns out that it is not necessary to declare the VSELECT signal as
GPIO and let the PMIC driver set it to a fixed high level. This switches
the voltage between 3.3V and 1.8V by setting the PMIC register for LDO5
accordingly.
Instead we can do it like other boards already do and simply mux the
VSELECT signal of the USDHC interface to the pin. This makes sure that
the correct voltage is selected by setting the PMIC's SD_VSEL input
to high or low accordingly.
