Some platforms has very small sram to run spl code, so
it may have no enough sapce for so much malloc pool before
relocation in spl stage as the normal u-boot stage.
Use CONFIG_VAL(SYS_MALLOC_F_LEN) to fit this condition.

Changes in v3:
- use CONFIG_VAL(), which suggested by Simon
Changes in v2: None
