clk: meson: clk-pll: fix initializing the old rate (fallback) for a PLL

[ Upstream commit 2f290b7c67 ]

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 rate again.
