arch/x86/acpigen: Fix corner case in _ROM generator
In case the Option ROM isn't a multiple of 4KiB the last buffer was
truncated to prevent a buffer overrun. But tests on nouveau showed
that nouveau expects a buffer that has the requested size and is zero
padded instead.
Always return a buffer with requested size and zero pad the remaining
bytes. Fixes nouveau on Lenovo W520 with Option ROM not being multiple
of 4 KiB.
