Subject: [PATCH v1 2/2] clk: rockchip: describe clk_gmac using the new muxgrf type on rk3328

With the newly introduced clk type for muxes in the grf we now can
describe some missing clocks, like the clk_gmac2io and clk_gmac2phy
that selects between clk_mac2io_src and gmac_clkin based on a bit
set in the general register files.
