Merge tag 'u-boot-stm32-20201125' of https://gitlab.denx.de/u-boot/custodians/u-boot-stmWIP/25Nov2020
- STM32 MCU's DT update
- Add DHCOM based STM32MP15x PicoITX board
- Correct ALIGN macro usage for on syram for SPL dcache support
- Fixes on DHCOM: uSD card-detect GPIO and Drop QSPI CS2
- Fix compilation issue for spl_mmc_boot_partition
- Fix MTD partitions for serial boot
- Add support of MCU HOLD BOOT with reset for stm32 remoteproc
(prepare alligneent with kernel DT)
- Correct bias information and support in STM32 soc and STMFX
- Support optional vbus in usbphyc
- Update FIT examples to avoid kernel zImage relocation before decompression
