[PATCH 4/4] drm/rockchip: dw_hdmi: Drop superfluous assignments of mpll_cfg, cur_ctr and phy_config

The mpll_cfg, cur_ctr and phy_config members in struct dw_hdmi_plat_data
are only used to configure the Synopsys PHYs supported internally by DW
HDMI transmitter driver (gpu/drm/bridge/synopsys/dw-hdmi.c), via
hdmi_phy_configure_dwc_hdmi_3d_tx(), which is further invoked from
dw_hdmi_phy_init().  This is part of the internal
dw_hdmi_synopsys_phy_ops struct, managed within dw_hdmi_detect_phy().

To handle vendor PHYs, DW HDMI driver doesn't make use of the internal
PHY ops and, instead, relies on the glue layer to provide the phy_ops
and phy_name members of struct dw_hdmi_plat_data.

Drop the unnecessary assignments of DW internal PHY related members from
structs rk3228_hdmi_drv_data and rk3328_hdmi_drv_data, since both set
the phy_force_vendor flag and correctly provide the expected vendor PHY
data.
