arm64: dts: ti: k3-am62x-phyboard-lyra: Add HDMI bridge regulators

Browse Source 
Specify I/0 voltage & core supply regulators used by the SII902x
HDMI bridge and make them known to the bridge.
This resolves the following warning:

  sii902x 1-0039: supply iovcc not found, using dummy regulator
  sii902x 1-0039: supply cvcc12 not found, using dummy regulator
