media: rzg2l-cru: Replace has_stride with stride_align field

RZG2L_CRU_STRIDE_ALIGN hardcodes an alignment only RZ/G3E and RZ/V2H
need, as only they have an AMnIS register.

Store the alignment into rzg2l_cru_info instead: 128 on RZ/G3E, 1 on
RZ/G2L, and update the code accordingly.

No functional change intended.
