231401de2e imx: imx8qm/imx8qxp: Power down the resources before SPL jump to u-boot
Make sure that all devices that are powered up by SPL are powered down
before entering into the u-boot. Otherwise the subsystem/device will
never be powered down by SCFW, due to SPL and u-boot are in different
partitions.

Benefiting from power domain driver, this patch implements the function
"imx8_power_off_pd_devices" to power off all active devices.

168fff26a8 imx8qxp_mek: Start with USDHC2 unpowered
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.

e5b8f7e665 imx8qxp: mek: enable dm-spl for pm
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.

018e3fd2d1 imx8qxp: mek: default enable SPL
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.
