Some clocks only can be accessed if their parent is enabled. mipi_csi_xx
clocks on SC9863A are an examples. We have to ensure the parent clock is
enabled when reading those clocks.

clk: sprd: add gate for pll clocks2020-03-25T02:03:56+00:00Xiaolong Zhangxiaolong.zhang@unisoc.com2020-03-04T07:27:24+00:00urn:sha1:187e5cd2d133771e978e7e4ea6aa684dfd1ce6ab
Some sprd's gate clocks are used to the switch of pll, which
need to wait a certain time for stable after being enabled.

Some clocks on the Spreadtrum's SoCs are just simple gates. Add
support for those clocks.
