From: Chunyan Zhang <[e-mail]>

Add SC9863A specific clock driver and devicetree bindings for it.

Also this patchset added support gate clock for pll which need to
wait a certain time for stable after being switched on.

Changes from v2:
* Addressed comments from Stephen:
- Remove ununsed header file from sc9863a-clk.c;
- Added comments for clocks which were marked with CLK_IGNORE_UNUSED,
  and removed some unnecessary CLK_IGNORE_UNUSED;
- Added error checking for sprd_clk_regmap_init().

* Addressed comments from Rob:
- Put some clocks under syscon nodes, since these clocks have the same
  physical address base with the syscon;
- Added clocks maxItems and listed out clock-names.

* Added Rob's reviewed-by on patch 4.

Changes from v1:
* Addressed comments:
- Removed redefine things;
- Switched DT bindings to yaml schema;
- Added macros for the new way of specifying clk parents; 
- Switched to use the new way of specifying clk parents;
- Clean CLK_IGNORE_UNUSED flags for some SC9863A clocks;
- Dropped the module alias;
- Use device_get_match_data() instead of of_match_node();

* Added Rob's Acked-by on patch 2.
