arm64: dts: imx8mp-evk: Add NXP LVDS to HDMI adapter cards

Browse Source 
One ITE IT6263 LVDS to HDMI converter is populated on NXP IMX-LVDS-HDMI
and IMX-DLVDS-HDMI adapter cards.

Card IMX-LVDS-HDMI supports single LVDS link(IT6263 link1).
Card IMX-DLVDS-HDMI supports dual LVDS links(IT6263 link1 and link2).

Only one card can be enabled with one i.MX8MP EVK.

Add dedicated overlays to support the below four connections:
1) imx8mp-evk-lvds0-imx-lvds-hdmi.dtso:
   i.MX8MP EVK LVDS0 connector <=> LVDS adapter card J6(IT6263 link1)

2) imx8mp-evk-lvds1-imx-lvds-hdmi.dtso:
   i.MX8MP EVK LVDS1 connector <=> LVDS adapter card J6(IT6263 link1)

3) imx8mp-evk-lvds0-imx-dlvds-hdmi-channel0.dtso:
   i.MX8MP EVK LVDS0 connector <=> DLVDS adapter card channel0(IT6263 link1)
   i.MX8MP EVK LVDS1 connector <=> DLVDS adapter card channel1(IT6263 link2)

4) imx8mp-evk-lvds1-imx-dlvds-hdmi-channel0.dtso:
   i.MX8MP EVK LVDS1 connector <=> DLVDS adapter card channel0(IT6263 link1)
   i.MX8MP EVK LVDS0 connector <=> DLVDS adapter card channel1(IT6263 link2)
