msm_fb: HDMI: Fix for high HDMI sleep current

In certain cases, the HPD circuitry is not switched off when the
device goes to suspend state, resulting in high sleep current on
the HDMI power rail. This patch ensures that the HPD circuitry is
always turned off during suspend operation by removing an
unnecessary condition check.
