arm/dt: msm8974: hdmi: add p-handle to hdmi tx device node

The pHandle is being added to enable MHL-HDMI interaction
through device tree. So that HDMI Tx can be programmed to
display appropriate video formats in the presence of MHL Tx.
Through this mechanism MHL driver receives a callback to
check HDMI TMDS status later during RAP message transactions.
