ASoC: sh: fsi: remove runtime register check from fsi_reg_xxx

Current FSI driver was checking register range on fsi_reg_xxx function.
This runtime check was added to avoid an illegal access
from wrong/mistake implementation.
But it is useless check under the correct implementation.
This patch escape runtime check by using macro technique.
If there is wrong implementation, it will be compile error.
