zynq: zc770_xm010: Decrease initial malloc size

This patch decreases initial malloc size as keeping
it more decreases the init stack size and hence
causing exception due to stack overflow. Also 0x800
should be fine for malloc before relocation.
The initial stack pointer is calculated as below.
                                 CONFIG_SYS_INIT_RAM_SIZE - \
                                 GENERATED_GBL_DATA_SIZE)
