rockchip: Use common bss and stack addresses on RK3399
With the stack and text base used by U-Boot SPL and proper on RK3399
there is a high likelihood of overlapping when U-Boot proper + FDT nears
or exceeded 1 MiB in size.
Currently the following memory layout is typically used on RK3399:
[ 0, 256K) - SPL binary
[ 256K, 2M) - TF-A / reserved
[ 2M, +X) - U-Boot proper binary (TEXT_BASE)
[ -X, 3M) - U-Boot proper pre-reloc stack (CUSTOM_SYS_INIT_SP_ADDR)
[ -16K, 3M) - pre-reloc malloc heap (SYS_MALLOC_F_LEN)
[ -X, 4M) - SPL pre-reloc stack (SPL_STACK)
[ -16K, 4M) - pre-reloc malloc heap (SPL_SYS_MALLOC_F_LEN)
[ 4M, +8K) - SPL bss (SPL_BSS_START_ADDR, SPL_BSS_MAX_SIZE)
[ -X, 64M) - SPL reloc stack (SPL_STACK_R_ADDR)
[ 63M, 64M) - reloc malloc heap (SPL_STACK_R_MALLOC_SIMPLE_LEN)
SPL can safely load U-Boot proper + FDT to [2M, 4M-16K) with this layout.
However, the stack at [-X, 3M) used during U-Boot proper pre-reloc is
restricting the safe size of U-Boot proper + FDT to be less than 1 MiB.
Migrate to use common bss, stack and malloc heap size and addresses to
fix this restriction and allow for a larger U-Boot proper image size.
