Use the ATAG info provided by the Rockchip binary TPL to identify RAM banks on the 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.
I intended this to be an RFC the first time I submitted it, so I'm correcting that mistake now. Additionally I have reduced a lot of the ATAGS code to only focus on the few bits we need in this case.
