[PATCH] kontron_pitx_imx8m: enlarge SYS_MALLOC_F_LEN

[Heiko Thiery <heiko.thiery@gmail.com>]

There is "alloc space exhausted" that can be seen with DEBUG_UART
options enabled and leeds to an non-functional board.

CONFIG_DEBUG_UART_BASE=0x30880000   # for serial3
CONFIG_DEBUG_UART_CLOCK=24000000

It is because CONFIG_SYS_MALLOC_F_LEN is too small, enlarge it. And set
CONFIG_SPL_STACK to 0x188000 to not waste the top 16bytes.
