clk: renesas: r8a779g0: Fix HSCIF parent clocks

[ Upstream commit a9003f74f5a2f487e101f3aa1dd5c3d3a78c6999 ]

As serial communication requires a clean clock signal, the High Speed
Serial Communication Interfaces with FIFO (HSCIF) is 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 V4H Hardware User's Manual rev. 0.54.
