clk: at91: sama7g5: Allocate only the needed amount of memory for PLLs

The maximum number of PLL components on SAMA7G5 is 3 (one fractional
part and 2 dividers). Allocate the needed amount of memory for
sama7g5_plls 2d array. Previous code used to allocate 7 array entries for
each PLL. While at it, replace 3 with PLL_COMPID_MAX in the loop which
parses the sama7g5_plls 2d array.
