clk: rockchip: add helper to register auxiliary GRFs

Browse Source 
Add rockchip_clk_add_grf() as a helper to register an auxiliary GRF
into the clock provider's aux_grf_table. This encapsulates the
struct rockchip_aux_grf allocation and hashtable insertion, so SoC
clock drivers do not need to open-code it.
