Increase the SPL_STACK_R_MALLOC_SIMPLE_LEN to 0x200000 to accommodate the
size of tispl.bin fit image. With the recent upgrade of ti-linux-firmware
from version v9.1.0 to v9.2.5, the size of tispl.bin fit image has
increased to 1.4MB, causing allocation errors in the R5 SPL:
```
alloc space exhausted
Could not get FIT buffer of
1325056 bytes
check CONFIG_SPL_SYS_MALLOC_SIZE
```
