drm/rockchip: dw_hdmi: Fix reading EDID when using a forced mode
EDID cannot be read on RK3328 until after read_hpd has been called and
correct io voltage has been configured based on connection status.
When a forced mode is used, e.g. video=1920x1080@60e, the connector
detect ops, that in turn normally calls the read_hpd, never gets called.
This result in reading EDID to fail in connector get_modes ops.
Call dw_hdmi_rk3328_read_hpd at end of dw_hdmi_rk3328_setup_hpd to
correct io voltage and allow reading EDID after setup_hpd.
