[PATCH 2/2] clk: samsung: acpm: add initial Exynos850 support

[Alexey Klimov]

The Exynos850 SoC utilizes the APM co-processor for clock management
via ACPM, similar to the GS101 SoC.

Add the Exynos850-specific clock variant array (including mif, int,
cpucl0, cpucl1, g3d, aud, cam, disp, and cp) and wire it up to the
driver data infrastructure. Add the "exynos850-acpm-clk" device ID
to enable dynamic instantiation of these clocks during probe().
