Subject: [PATCH v2 0/5] DRM: Bridge: DW_HDMI: Add new features and bug fix

This is new features and bug fix patch set for DW_HDMI DRM bridge driver
that has verified by NXP i.MX8MPlus.
Three new feature added:
1. Add GPA interface for DW_HDMI Audio.
2. Add CEC PM functions to restore CEC status when device suspend/resume
3. New API for reset PHY Gen1.
Two bugs fixed:
1. Enable overflow workaround for all IP versions later than v1.30a.
2. Clear GCP_Auto bit for 24-bit color depth to pass CTS.

v1->v2:
1. Save CEC interrupt registers in struct dw_hdmi_cec
2. Restore CEC logical address register by cec->addresses.
3. Default enable overflow workaround for all versions later than v1.30a.
4. Add clear_gcp_auto flag to clear gcp_auto bit for all 24-bit color.
5. Remove i.MX8MPlus specific reference.
