[PATCH 1/3] clk: meson: clk-pll: fix initializing the old rate (fallback) for a PLL

[Martin Blumenstingl <martin.blumenstingl@googlemail.com>]

The "rate" parameter in meson_clk_pll_set_rate() contains the new rate.
Retrieve the old rate with clk_hw_get_rate() so we don't inifinitely try
to switch from the new rate to the same ratte again.
