[PATCH 2/2] drm/bridge: th1520-dw-hdmi: Fix remove() callback

[Felix Gu <ustc.gu@gmail.com>]

This driver stores struct th1520_hdmi * in platform drvdata, but
th1520_dw_hdmi_remove() was reading it back as struct dw_hdmi *
and passing it to dw_hdmi_remove(), so teardown runs on the wrong
pointer.

Retrieve struct th1520_hdmi * from platform drvdata and pass
hdmi->dw_hdmi to dw_hdmi_remove().

Fixes: 96f30ee0fb9d ("drm/bridge: add a driver for T-Head TH1520 HDMI controller")
