ARM: tegra: clock: support get and set rate for simple PLL

Simple PLL clocks like PLLD2 were omitted since they do not share common
4 register structure with main clocks. Such clocks are containd in simple
PLL group. Only clock_start_pll function supported them. This patch expands
this support on clock_set_rate and clock_get_rate which should make
simple PLL clocks equal to main PLL clocks.
