Subject: [PATCH v1 10/50] clk: samsung: change ACLK100_NOC clocks
 definitions Exynos5x

The ACLK100_NOC has different topology in Exynos5420 and 5422/5800.  In
Exynos5420 this clock divider has 3 bits while in 5422/5800 has 4 bits.
The patch adds needed dividers in the exynos5800_div_clks, updates
exynos5x_div_clks and exynos5420_div_clks properly. It also adds IDs to
manage clocks from DT.
