clk: at91: sam9x7: update pll clk ranges

Browse source 
Update the min, max ranges of the PLL clocks according to the latest
datasheet to be coherent in the driver. This patch solves the issues in
configuring the clocks related to peripherals with the desired frequency
within the range.

Fixes: 33013b43e2 ("clk: at91: sam9x7: add sam9x7 pmc driver")
