[PATCH] clk: mvebu: adjust AP806 CPU clock frequencies to production chip

[Thomas Petazzoni]

This commit adjusts the list of possible "Sample At Reset" values that
define the CPU clock frequency of the AP806 (part of Marvell Armada
7K/8K) to the values that have been validated with the production
chip. Earlier values were preliminary.
