[PATCH V2] Kconfig: enlarge CONFIG_SYS_MALLOC_F_LEN

From: Peng Fan <peng.fan@nxp.com>

"alloc space exhausted" happens in very early stage, which could be seen
with DEBUG_UART options enabled and leeds to an non-functional board.

kontron_pitx_imx8m:
CONFIG_DEBUG_UART_BASE=0x30880000 # for serial3
CONFIG_DEBUG_UART_CLOCK=24000000

imx8mqevk:
CONFIG_DEBUG_UART_BASE=0x30860000 # for uart1
CONFIG_DEBUG_UART_CLOCK=24000000

It is because CONFIG_SYS_MALLOC_F_LEN is too small and still leave
CONFIG_SPL_SYS_MALLOC_F_LEN as 0x2000.
