ASoC: intel: board: sof_rt5682: Update rt1015 pll input clk freq

In commit d696a614 ("ASoC: rt1015: Add condition to prevent SoC
providing bclk in ratio of 50 times of sample rate."), PLL input at 50fs
is no longer supported, the new recommended settings at 48Khz rate are:

PLL input       SSP bclk
------------------------
64fs            3.073Mhz
100fs           4.8Mhz

(bclk update is reflected in topoplogy.)
