[PATCH RFC/RFT 04/12] clk: samsung: exynos7870: Use platform_driver_probe() to avoid __refdata

[Krzysztof Kozlowski]

Switch registering platform driver to platform_driver_probe(), so the
'struct platform_driver' can be properly discarded after init and there
won't be need of __refdata to silence DEBUG_SECTION_MISMATCH.

The change requires using subsys_initcall instead of core_initcall,
because no device drivers would bound in the latter, as required by
platform_driver_probe().
