Migrate RK3588 boards that exists in Linux v6.8 to use OF_UPSTREAM.
Following targets is not migrated to use OF_UPSTREAM:
- generic-rk3588: Generic target only meant for U-Boot use
- toybrick-rk3588: Merged in v6.9-rc1

RK3588-based devices now support creating DRAM banks with proper holes
by reading the ATAGS from Rockchip TPL blob, so let's use that mechanism
instead.
Since ft_board_setup isn't defined anymore, there's no need for
selecting CONFIG_OF_BOARD_SETUP.
Similarly, because the evb_rk3588.c would be empty, it is simply
removed, with the (would-be-empty) Makefile as well.
The CONFIG_NR_DRAM_BANK now defaults to 10 which is a safe bet for
reading banks from ATAGS, so let's use the default value instead.
All defconfigs using the CONFIG_TARGET_EVB_RK3588 are updated at once
since they are impacted by this change.

Currently the following memory layout is typically used on RK3588:
[ 0, 256K) - SPL binary
[ 256K, 2M) - TF-A / reserved
[ -X, 4M) - SPL pre-reloc stack (SPL_STACK)
[ 3.5M, 4M) - pre-reloc malloc heap (SPL_SYS_MALLOC_F_LEN)
[ -X, 6M) - SPL reloc stack (SPL_STACK_R_ADDR)
[ 5M, 6M) - reloc malloc heap (SPL_STACK_R_MALLOC_SIMPLE_LEN)
[ 10M, +X) - U-Boot proper binary (TEXT_BASE)
[ -X, 12M) - U-Boot proper pre-reloc stack (CUSTOM_SYS_INIT_SP_ADDR)
[11.5M, 12M) - pre-reloc malloc heap (SYS_MALLOC_F_LEN)
[ 64M, +16K) - SPL bss (SPL_BSS_START_ADDR, SPL_BSS_MAX_SIZE)
SPL can safely load U-Boot proper + FDT to [10M, 11.5M) with this layout.
However, on ROCK 5A the SPL stacks is overlapping:
[ -X, 16M) - SPL pre-reloc stack (SPL_STACK)
[15.5M, 16M) - pre-reloc malloc heap (SPL_SYS_MALLOC_F_LEN)
[ -X, 16M) - SPL reloc stack (SPL_STACK_R_ADDR)
[ 15M, 16M) - reloc malloc heap (SPL_STACK_R_MALLOC_SIMPLE_LEN)
Because bind and probe udevice instanses is allocated on the pre-reloc
malloc heap, there is going to be an overlap when reloc malloc heap
reaches close to 512 KiB of usage.
Migrate to use common bss, stack and malloc heap size and addresses to
mitigate these limitations and allow for a larger U-Boot proper size.
