clk: rockchip: rk3128: Fix aclk_peri_src's parent
[ Upstream commit 98dcc6be3859fb15257750b8e1d4e0eefd2c5e1e ]
According to the TRM there are no specific gpll_peri, cpll_peri,
gpll_div2_peri or gpll_div3_peri gates, but a single clk_peri_src gate.
Instead mux_clk_peri_src directly connects to the plls respectively the pll
divider clocks.
Fix this by creating a single gated composite.
Also rename all occurrences of aclk_peri_src to clk_peri_src, since it
is the parent for peri aclks, pclks and hclks. That name also matches
the one used in the TRM.
