boards/nucleo-h743zi: remove write buffering from bootloader configs
Remove CONFIG_FTL_WRITEBUFFER, CONFIG_DRVR_WRITEBUFFER,
CONFIG_DRVR_READAHEAD, and CONFIG_DRVR_INVALIDATE from the
nxboot-loader and mcuboot-loader defconfigs.
FTL write buffering delays physical flash commits, which can cause
data loss on power failure during OTA updates. Bootloaders require
immediate write durability and should not use buffered writes.
