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")

Hi Krzysztof,

thanks for your quick feedback.

You're right: This series mixes up too many things. I'll split up and 
re-send.

(And fix my typos, indeed)

Best Regards,

Alex
