We should really do the reset of i2c before we set the speed. There are
no actual known problems fixed by this, but it seems like a good idea
and the latest upstream patch does this.

DDC have two modes: fast mode, standard mode. The previous ddc support
patch(https://chromium-review.googlesource.com/#/c/292012/) configure
the ddc to fast mode.
It works rightly in most HDTV case, but I found that ddc would always
failed if I used the VGA->HDMI adapter. And after I switch ddc to
standard mode, no failed anymore. I believe the standard mode could
provide better compatibility.

In (3b9ba9a FROMLIST: drm: bridge/dw_hdmi: add dw hdmi i2c bus adapter
support) we added a new i2c bus adapter but no of_node was provided to
the adapter. This made it difficult to assign a bus number to the
adapter in the device tree.
Because of the fact that dynamic bus numbering of i2c starts at 0 and
the fact that i2c busses are no longer allowed to be loaded extra-early
at boot (because deferred probe solves the boot order problem), it's
possible that this could cause the DDC i2c bus to get ID 0 and could
cause later SoC i2c busses to fail to probe because they're expecting to
get ID 0.
Note that probe ordering of mickey is slightly different than probe
ordering of other veyron devices, which is why this only shows up on
mickey.

The change adds support of internal HDMI I2C master controller, this
subdevice is used by default, if "ddc-i2c-bus" DT property is omitted.
The main purpose of this functionality is to support reading EDID from
an HDMI monitor on boards, which don't have an I2C bus connected to
DDC pins.
The current implementation does not support "I2C Master Interface
Extended Read Mode" to read data addressed by non-zero segment
pointer, this means that if EDID has more than 1 extension blocks,
EDID reading operation won't succeed, in my practice all tested HDMI
monitors have at maximum one extension block.

hdmi->disabled maybe not match to the real hardware status.
->dw_hdmi_bridge_enable()
hdmi->disabled = false;
-->dw_hdmi_update_power()
if (hdmi->rxsense)
force = DRM_FORCE_ON;
else
force = DRM_FORCE_OFF;
hdmi->rxsense maybe false on bridge enable path, then hdmi->disabled
is false, but actually hardware is power off, they are not match.
So on dw_hdmi_irq, judge the hardware status with hdmi->disabled is wrong.
This bug would cause display lost, unplug/plug can't recovery display.

host->card_busy() was introduced for SD voltage switching which checks all
4 data lines.
Increasingly, host->card_busy is being used to poll the the busy signal
which is only data line 0 (DAT[0]).
The current logic in sdhci_card_busy() does not work in that case because
it returns false if any of the data lines is high. It also ignores
possibilities:
- data lines 1-3 are not connected and could show at any level
- data lines 1-2 can be used by SDIO for other purposes
According to the SD specification, it is OK to check any of the data lines
for voltage switching, so change to use DAT[0] only.
