arm64: dts: mt8192-asurada-spherion: Add Synaptics trackpad support
Some spherion variants use Synaptics trackpad at address 0x2c in the
I2C2 bus with the generic HID-over-i2c driver, and this cannot be
distinguished from the firmware compatible string.
Support both trackpads in the same devicetree by moving the trackpad
pinctrl property to i2c2 and adding the node for Synaptics trackpad.
