clk: mvebu: Fix clk frequency value if SSCG is enabled When the SSCG (Spread Spectrum Clock Generator) is enabled, it shifts the frequency of the clock. The percentage is no more than 1% but when the clock is used for a timer it leads to a clock drift. This patch allows to correct the affected clock when the SSCG is enabled. The check is done in an new optional function related to each SoC: is_sscg_enabled(). The fix is done with the other new optional function related to each SoC: fix_sscg_deviation. If one these functions are not present then no correction is done on the clock frequency.
