clk: samsung: exynos542x: Add EPLL rate table
A specific clock rate table is added for EPLL so it is possible to set frequency of the EPLL output clock as multiple of various audio sampling rates. Reviewed-by: Krzysztof Kozlowski <krzk@kernel.org> Signed-off-by: Sylwester Nawrocki <s.nawrocki@samsung.com>
