If the value of cec 0x16 register(dsi pclk divider) is not
configured correctly,dsi-hdmi display through bridge chip
can't be up. So set automatic pclk divider to this register
to apply for all resolution cases from DSI.

This implementation adds the following support:
1. handle bridge chip error reported by driver to DBA. error reported
to DBA will be send to recovery manager to recover the faulty
bridge chip by performing a power cycle.
2. smmu fault error notification.
3. detection on errors in bridge chip driver.

VREG was enabled during init and never turn off until the bridge chip
unregister. We need to add VREG on/off sequence into bridge chip
power on/off in order to reduce platform current draw.

For some platforms, after turning on the VREG for ADV7533 bridge
chip, need to sleep some period of time before doing any
I2C transactions with the bridge chip.

If there is any failure while registering a DBA client with MDSS
driver, then remove the client from device client list first and
then free the client. Otherwise driver might crash when
traversing the device client list in later stage, because of an
uninitialized entry in the list.

In the current implementation adv regulator get is called
from DBA driver but regulator enable or disable is never getting
called. So because of this there is power leakage in the
HDMI path. This change fixes the issue by properly configuring
the adv regulator in DBA driver.

In current implementation we are ignoring check revision
failure for ADV7533 probe which might be because the chip
itself is not connected to platform. Due to this we are not
disabling the power supply even though chip is not connected
and going ahead causing power leakage. This change fixes the
same.

Currently, DBA (Display Bridge Abstract) related functionality
is being used in DSI files. Carve out DBA related functionality
into a new file which serves as a utility module and can be used
by any MDSS driver.
Define CEC on/enable functions in DBA (Display Bridge Abstract) so that
clients can enable disable CEC based on other dependent CEC modules.
Separate out CEC abstract data with CEC driver data and initialize and
release corresponding modules properly.
