arm64: dts: qcom: sc8280xp: rename qup2_i2c5 to i2c21

In preparation for adding the missing SPI and I2C nodes to
sc8280xp.dtsi, it was decided to rename all of the existing qupX_
uart, spi, and i2c nodes to drop the qupX_ prefix. Let's go ahead
and rename qup2_i2c5 to i2c21. Under the old name, this was the 5th
index under qup2, which starts at index 16.

Note that some nodes are moved in the file by this patch to preserve
the expected sort order in the file. Additionally, the properties
within the pinctrl state node are sorted to match the expected order
that's typically done in other DTs.
