Subject: [PATCH 2/3] arm64: dts: qcom: sdm845-db845c: correct SPI2 pins drive strength

The pin configuration (done with generic pin controller helpers and
as expressed by bindings) requires children nodes with either:
1. "pins" property and the actual configuration,
2. another set of nodes with above point.

The qup_spi2_default pin configuration used second method - with a
"pinmux" child.

Fixes: 8d23a0040475 ("arm64: dts: qcom: db845c: add Low speed expansion i2c and spi nodes")
