F-7381: fail SAMA5D3 NAND write/erase instead of reporting success 

ext_flash_write() and ext_flash_erase() discarded their arguments and
returned 0, so any update flow that reaches this HAL was told an
erase/program succeeded while the NAND contents were left untouched.

NAND page program and block erase are not implemented for this target;
report failure so callers that branch on the result can detect it
instead of continuing with a write that never happened. The read-only
boot path is unaffected.
