Subject: [PATCH] clk: rockchip: Fix clock gate for rk3188 hclk_emem_peri

Do not disable clock gate "hclk_emem_peri", otherwise EMAC clocks no longer work
and it breaks ethernet on RK3066 and RK3188. It fixes a regression introduced by
commit 78eaf6095cc763c1a228ebac5682852f04e85205 ("clk: rockchip: disable unused clocks").
