Use the ATAG info provided by the Rockchip binary TPL to identify RAM banks on the RK3568 and RK3588 when using the ROCKCHIP_TPL binary.
This is needed because there are specific addresses that should not be written to for all RK3588 based devices with >=16GB of RAM, writing to these addresses immediately results in a crash. Additionally on the RK3568 and RK3588 this allows us to reclaim 256MB of RAM when RAM >= 4GB.
Changes since V1: - After additional feedback, removed RFC tag. - Made code work for both RK3568 and RK3588. - Removed memory hole code for all RK3588 boards. - Updated CONFIG_NR_DRAM_BANKS for 3568 and 3588 boards as it is the max number of banks supported by the ATAGS code.
