imx8: scu_api: sync sc_rm_is_pad_owned api change

SCFW has fixed a overflow issue in sc_rm_is_pad_owned API. This
requires u-boot to update API implementation, since it will cause
compatible issue. Otherwise all pad checking will have problem and
cause pad setting not continue.

Due to the compatible issue, the new u-boot only works with new
SCFW (API version: 1.21 and later).

old scfw + old u-boot: API overflow issue
old scfw + new u-boot, or new scfw + old u-boot: API compatible issue
new scfw + new u-boot: Working
