[PATCH v3 4/4] arm64: dts: fix SPI drive strength values as per FSD HW UM

[Padmanabhan Rajanbabu <p.rajanbabu@xxxxxxxxxxx>]

Drive strength values used for SPI is not reflecting the default values
recommended by FSD HW UM.

Fix the drive strength values for SPI, thereby ensuring that the existing
device tree file is using default drive strength values recommended by UM
for FSD SoC.

Fixes: 684dac402f21 ("arm64: dts: fsd: Add initial pinctrl support")
