clk: renesas: r8a779f0: Fix HSCIF parent clocks

Browse Source 
[ Upstream commit c258e3ab63 ]

As serial communication requires a clean clock signal, the High Speed
Serial Communication Interfaces with FIFO (HSCIF) are clocked by a clock
that is not affected by Spread Spectrum or Fractional Multiplication.

Hence change the parent clocks for the HSCIF modules from the S0D3_PER
clock to the SASYNCPERD1 clock (which has the same clock rate), cfr.
R-Car S4-8 Hardware User's Manual rev. 0.81.
