On RZ/G3E, TSSEL register field is 8 bits wide compared to 7 on RZ/V2H. Also bits 8..14 is reserved on RZ/G3E and any writes on these reserved bits is ignored. Use the bitmask GENMASK(field_width - 2, 0) on both SoCs for extracting TSSEL and we can drop the macros ICU_TSSR_TSSEL_PREP and ICU_TSSR_TSSEL_MASK.
