ARM: stm32: fix PRE_CON_BUF_ADDR on STM32MP13
Since SYS_MALLOC_F_LEN increasing to 0x2100000 on STM32MP13, the
pre-console buffer is overlapped by stack (0xC0400000 + 0x2100000),
so the this buffer must be moved just before the bootstage to avoid issue.
After this patch the pre-relocation memory mapping for STM32MP13x is:
C3000000 = Bootstage CONFIG_BOOTSTAGE_STASH_ADDR
C2FFF000 = PreConsole CONFIG_PRE_CON_BUF_ADDR
with size CONFIG_PRE_CON_BUF_SZ = 4096
C0400000 = start for stack with CONFIG_CUSTOM_SYS_INIT_SP_ADDR
including CONFIG_SYS_MALLOC_F_LEN
C0000000 = Load Address of U-Boot with CONFIG_TEXT_BASE
Fixes: 93c962c7af7e ("configs: stm32mp13: increase SYS_MALLOC_F_LEN to 0x210000")
