Subject: [PATCH 2/3] clk: samsung: exynos5420/5250: Add IDs to the CPU
 parent clk definitions

Precedence: bulk

Use non-zero clock IDs in definitions of the CPU parent clocks
for exynos5420, exynos5250 SoCs. This will allow us to reference
the parent clocks directly in the driver by cached struct clk_hw
pointers, rather than doing clk lookup by name.
