Subject: clk: mvebu: adjust AP806 CPU clock frequencies to production chip

From: Thomas Petazzoni <[email protected]>

[ Upstream commit 0c70ffc5f300e7c3a1a76ca0530860574afc890b ]

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.
