drm/msm/hdmi: drop hpd_regs usage on 8x74/8084
The MSM HDMI driver has support for hpd_regs on 8x74/8084: supply
regulators that are to be enabled for HPD to work. Currently these
regulators contain the hpd_gdsc, which was replaced by the power-domains
support and hpd-5v/hpd-5v-en, which are not used by the chip itself.
They power up the ESD bridge.
However it is a separate device which should be represented separately
in the device tree.
None of upstreamed devices support these properties. Thus drop support
for them from the HDMI driver.
