arm64: dts: renesas: r8a779f0: Fix SCIF "brg_int" clock

[ Upstream commit 64416ef ] As serial communication requires a clean clock signal, the Serial Communication Interfaces with FIFO (SCIF) are clocked by a clock that is not affected by Spread Spectrum or Fractional Multiplication. Hence change the clock input for the SCIF Baud Rate Generator internal clock 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. Fixes: c62331e ("arm64: dts: renesas: Add Renesas R8A779F0 SoC support") Fixes: 4075314 ("arm64: dts: renesas: r8a779f0: Add SCIF nodes") Reported-by: Geert Uytterhoeven <geert+renesas@glider.be> Signed-off-by: Wolfram Sang <wsa+renesas@sang-engineering.com> Link: https://lore.kernel.org/r/20221103143440.46449-5-wsa+renesas@sang-engineering.com Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Signed-off-by: Sasha Levin <sashal@kernel.org>
