Subject: [PATCH 05/31] clk: rockchip: rk3128: Fix aclk_peri_src parent

From: Finley Xiao <finley.xiao@...k-chips.com>

According to the TRM there are no specific cpll_peri, gpll_div2_peri or
gpll_div3_peri gates, but a single clk_peri_src gate and the peri mux
directly connects to the plls respectivly 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 both peri aclks and hclks and that also matches the
naming in the TRM.

Fixes: f6022e88faca ("clk: rockchip: add clock controller for rk3128")

[renamed aclk_peri_src -> clk_peri_src and added commit message]
