clk: rockchip: allow grf_type_sys lookup in aux_grf_table

Remove the grf_type_sys exclusion from the auxiliary GRF table lookup
in rockchip_clk_register_branches(). Previously, branches with
grf_type_sys always used ctx->grf directly, bypassing the aux_grf_table.

This is a problem on SoCs like RK3588 where ctx->grf points to the
PHP_GRF (set via the CRU's rockchip,grf phandle), but GATE_GRF clock
entries need to access the SYS_GRF instead.

With this change, grf_type_sys branches first check the aux_grf_table,
and fall back to ctx->grf if no entry is found. This is backwards
compatible: on SoCs that do not register grf_type_sys in the
aux_grf_table, the behavior is unchanged.
