To enable splash at A53 SPL, need to do memory map changes which
involves locate stack above malloc and have enough space to load bmp
image above stack. To load a 1920X1200 image a minimum of 8.8MB space is
needed, to support it move malloc down to 0x80b80000 from 0x80480000 and
bss to 0x80c80000 to have 1MB buffer between malloc and BSS.
Observed SPL size 195KB, CONFIG_SPL_SIZE_LIMIT set to 256KB.
Observed stack size 1904Bytes, CONFIG_SPL_SIZE_LIMIT_PROVIDE_STACK set
to 2KB.
CONFIG_SPL_SYS_REPORT_STACK_F_USAGE config sets stack above the malloc
and reports for stack overflow.
