[U-Boot] [PATCH v2 5/9] rockchip: set malloc pool size to 0 before relocation in spl state on rk3036 based board

RK3036 only has 4kb sram, the spl code will use
3.4 ~ 3.5 kb, the last 0.5kb are used for SP and
GD, so there is no space for malloc. Also, the spl
will directly return to bootrom after dram initialized,
they never need the space for malloc.

Changes in v2:
- set spl pre relocation malloc pool by CONFIG_SPL_SYS_MALLOC_F_LEN
