Add SoC specific RAM bank logic for the rk3588 boards. This logic works by reading the ATAGS created by the ROCKCHIP_TPL stage and applies fixups on those to ensure we aren't stepping on any reserved memory addresses.
The existing logic requires us to define memory holes to allow devices with 16GB or more RAM to function properly, as well as blocking up to 256MB of otherwise accessible RAM.
Looks good at first glance, will runtime test later.
Please move this out from being RK3588 specific, my prior request to depend on !IS_ENABLED(CONFIG_ROCKCHIP_EXTERNAL_TPL) was so that this also gets used on RK356x. On 4 GiB RAM RK356x boards the same 256 MiB could be reclaimed with this.
For final patch submission please also remove all duplicated RK3588 board implementations of ft_board_setup() that adds reserved memory nodes to DT, they are no longer needed after this.
Regards, Jonas
