Some platforms have very limited SRAM to run SPL code, so there may not be the same amount space for a malloc pool before relocation in the SPL stage as the normal U-Boot stage. Make SPL and (the full) U-Boot stage use independent SYS_MALLOC_F_LEN, so the size of pre-relocation malloc pool can be configured memory space independently.
