After triggering a "reboot" command in Linux the following
hang in SPL is observed:
U-Boot SPL 2020.04 (Apr 15 2020 - 10:49:29 -0300)
Normal Boot
WDT: Not found!
Trying to boot from MMC2_2
spl: mmc init failed with error: -70
SPL: failed to boot from all boot devices
### ERROR ### Please RESET the board ###
This error happens because the CMD_ERR bit is set in the IRQ status
register after booting from Linux.
To ensure a fresh start, force the VMMC supply to get unpowered first.

with u-boot,dm-spl added for imx8qx-pm node, and SPL_SIMPLE_BUS enabled,
the bind and probe code in board file could be removed.
Also we need to enlarge SYS_MALLOC_F_LEN to avoid calloc fail.

Enable SPL for i.MX8QXP MEK, and currently use SPL FIT.
The SPL enable SPL_DM to use MMC/PINCTRL/POWER DOMAIN/CLK.
Note: SPL FIT could not support secure boot chain, because i.MX8/8X
only support i.MX container format. This container format has
not been upstreamed, so we use FIT for now. When SPL container
supported, we could switch to that.
