[v3,08/13] clk: at91: sama7d65: add sama7d65 pmc driver

From: Ryan Wanner <Ryan.Wanner@microchip.com>

Add clock support for SAMA7D65 SoC.

Increase maximum number of valid master clocks. The PMC for the SAMA7D65
requires 9 master clocks.

Increase maximum amount of PLLs to 9 to support SAMA7D65 SoC PLL
requirements.

I personally prefered the other variant where these were introduced as
individual preparatory patches.
