arm64: dts: imx8mp-evk: Add MX8-DLVDS-LCD1 display module support

Browse Source 
MX8-DLVDS-LCD1 display module integrates a KOE TX26D202VM0BWA LCD panel
and a touch IC.  Add an overlay to support the LCD panel on i.MX8MP EVK.
Specify 148.5MHz clock frequency in panel-timing node to accommodate
3.5-fold 519.75MHz media_ldb clock which is derived from 1.0395GHz
video_pll1 clock.
