arm64: dts: renesas: r8a779g0: Fix HSCIF0 "brg_int" clock

Browse source

[ Upstream commit a4290d407a ]

As serial communication requires a 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 clock input for the HSCIF0 Baud Rate Generator internal
clock 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.
