arm64: dts: qcom: qcs6490-rb3gen2: Enable 4-lane DisplayPort Alt Mode

Browse Source 
Add the mode-switch property to the QMP combo PHY so that mode-switch
events are routed to it, allowing the PHY to enter DisplayPort Alternate
Mode. Expand the DP data-lanes assignment from two to four lanes to make
use of the full link bandwidth available in this configuration.
