Subject: [RFT PATCH v4 0/2] clk: samsung: add common support for CPU clocks

These two patches were originally a part of the series [1]. They add
support to the common samsung clock driver to parse and register the
CPU clocks when provided. This allows for the samsung clock drivers to
simply provide a `struct samsung_cpu_clock` to `struct samsung_cmu_info`
and then call samsung_cmu_register_one(). With this new support, we can
now get rid of the custom apollo and atlas CLK_OF_DECLARE init functions.

Since I don't have the hardware to test these, I'm including the RFT tag
to try and get help testing and verifying these.

--
Changes in v4:
 - Updated 'struct samsung_cpu_clock' to reference the parent and alt_parent
   hw clocks via ID instead of name
 - Dropped __clk_lookup() in favor of ctx->clk_data.hw instead

Changes in v3:
 - Same as v1-v2
 - Tested-by: Marek Szyprowski <m.szyprowski@...sung.com>
