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")

Please send fixes as separate patchset. Don't mix it with other work and
definitely it should not be in the middle of the patchset.

Best regards,
Krzysztof

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
