[U-Boot] [PATCH v3 0/9] pico-imx7d: Add support for BL33 case

[Jun Nie]

Add configuration to boot U-boot as BL33 case. The boot flow
is ATF -> OPTEE -> U-boot.

Changes vs V2:
- Revise fix to UART clock ID.
- Add documentation of build and test for BL33 usage case.
- Add device tree to store public key for FIT image verfication usage.
- Add revert patch to LCD support. Pico-pi does not boot with it.
    I see it is suggested to be reverted in maillist.

Changes vs V1:
- Remove DCD file.
- Add a patch to fix uart clock root ID.
- Change file name from pico-pi-imx7d_bl33_defconfig to pico-imx7d_bl33_defconfig
