Update the SPL_STACK_R_MALLOC_SIMPLE_LEN which also including space for STACK and the size may not enough when loding FIT image in SPL.
If the size is not enough, you can see log like this when loding FIT:
U-Boot TPL 2020.01-rc3-00082-g4b19b89ca4-dirty (Dec 05 2019 - 11:52:53) Trying to boot from BOOTROM Returning to boot ROM... U-Boot SPL 2020.01-rc3-00082-g4b19b89ca4-dirty (Dec 05 2019 - 11:52:53 +0800) Trying to boot from MMC2
And if enable the DEBUG for everyting in SPL, the log will hang at dwmmc sending CMD16 for 'uboot' loadables binary because this step need a large stack cost(about 0x2d00).
