clk: sunxi-ng: sun55i-a523-ccu: Lower audio0 pll minimum rate

clk: sunxi-ng: sun55i-a523-ccu: Lower audio0 pll minimum rate

While the user manual states that the PLL's rate should be between 180
MHz and 3 GHz in the register defninition section, it also says the
actual operating frequency is 22.5792*4 MHz in the PLL features table.

22.5792*4 MHz is one of the actual clock rates that we want and is
is available in the SDM table. Lower the minimum clock rate to 90 MHz
so that both rates in the SDM table can be used.
