clk: Add common __clk_get(), __clk_put() implementations
This patch adds common __clk_get(), __clk_put() clkdev helpers which
replace their platform specific counterparts when the common clock
API is enabled.
The owner module pointer field is added to struct clk so a reference
to the clock supplier module can be taken by the clock consumers.

Changes since v5:
- none.

- dropped unnecessary struct module forward declaration from
clk-provider.h
Changes since v3:
- dropped exporting of __clk_get(), __clk_put().
Changes since v2:
- fixed handling of NULL clock pointers in __clk_get(), __clk_put();
