u-boot-radxa-rk3588/legacy: use 000.patching_config; fix boot from SD when combined with from-factory eMMC blobs (TEE mismatch)

• u-boot-radxa-rk3588/legacy: rewrite u-boot patches, no changes
• u-boot-radxa-rk3588/legacy: add 0000.patching_config.yaml and move all null-patches into dt and defconfig dirs as bare files
  • DTs and defconfigs should be identical to their null-patch equivalents
• u-boot-radxa-rk3588/legacy: rewrite nanopc_t6_defconfig -- no changes
  • CONFIG_REGULATOR_RK806=y seems a leftover that's not really used?
• u-boot-radxa-rk3588/legacy: rewrite nanopc_cm3588_defconfig -- no changes
  • CONFIG_REGULATOR_RK806=y seems a leftover that's not really used?
• u-boot-radxa-rk3588/legacy: nanopc_cm3588_defconfig: disable OPTEE (for OOB working boot with from-factory blobs in eMMC)
  • makes it compatible with vendor out-of-box blobs (which include TEE) in the from-factory eMMC
  • Armbian itself doesn't ship TEE blobs
  • when combining from-factory eMMC blobs with an Armbian SD card, TEE blobs are in practice found by u-boot
  • but then proceeds to fail with optee api revision is too low
  • disable OPTEE in defconfig fixes it, TEE isn't used in any way by Armbian
