configs/stm32f469_disco_{sd, xip}: fix boot failure after uClibc bump

Browse Source 
Since uClibc was bumped to 1.0.58 (c7fef3704c, "package/uclibc:
bump to 1.0.58"), the board fails to boot:

    sh: out of memory
    Kernel panic - not syncing: Attempted to kill init! exitcode=0x00000100
    ---[ end Kernel panic - not syncing: Attempted to kill init! exitcode=0x00000100 ]---

The STM32F469 has no MMU, and uClibc's standard malloc() implementation
returns NULL for allocations performed during early init on this target,
causing init to abort immediately.

Fix this by switching to MALLOC_SIMPLE, a plain mmap-based allocator
meant for small/noMMU systems, via the uClibc config fragment already
introduced for the STM32F429 in board/stmicroelectronics/common/stm32f4xx/,
which addresses the same issue on this Cortex-M4/noMMU board.
