clk: tegra: Fix T210 PLLRE registration

Switched Tegra210 PLLRE registration to common PLL ops instead of special
PLLRE ops used on previous Tegra chips. The latter ops do not follow
chip specific PLL frequency table, and do not apply chip specific rate
calculation method.

Removed unnecessary default rate setting that duplicates h/w reset
state, and is overwritten by clock initialization, anyway.
