Jiancheng Xue 322269163a clk: hisilicon: add hisi_clk_alloc function.
Before, there was an ordering issue that the clock provider
had been published in hisi_clk_init before it could provide
valid clocks to consumers. hisi_clk_alloc is just used to
allocate memory space for struct hisi_clock_data. It makes
it possible to publish the provider after the clocks are ready.

Uwe Kleine-König 4a1caed3d0 clk: make several parent names const
Since commit 2893c37946 ("clk: make strings in parent name arrays
const") the name of parent clocks can be const. So add more const in
several clock drivers.

Bintian Wang 72ea48610d clk: hi6220: Clock driver support for Hisilicon hi6220 SoC
Add clock drivers for hi6220 SoC, this driver controls the SoC
registers to supply different clocks to different IPs in the SoC.

We add one divider clock for hi6220 because the divider in hi6220
also has a mask bit but it doesnot obey the rule defined by flag
"CLK_DIVIDER_HIWORD_MASK", we can not get index of the mask bit by
left shift fixed bits (e.g. 16 bits), so we add this divider clock
to handle it.
