arm64: dts: ti: k3-am62a7-sk: Add interrupt support for IO Expander
The Hot Plug Detect (HPD) signal for the HDMI display travels from the
on-board HDMI connector, through the IO Expander 1, and finally to the
main_gpio1 GPIO 23, of the SoC.
Add interrupt information for the IO Expander 1 (exp1) along with the
relevant pinmux.
