Driver defers processing of BW scaling event if PM state is not in
M0. This delays the BW scaling to take effect. Fix this issue by
resuming the device if it was suspended state and assert wake DB.
After changing the BW of the link de-assert the wake DB.

Driver continues handling of MSI0 interrupt even if MHI register access
is not allowed. By doing so it calls the status call back and performs
early notification for the MHI client. This is not needed when MHI register
access is not allowed. Hence skip the handling in this case and return.

During fast suspend/resume, the power management states in MHI
can change to any error state. Allow for it by re-checking and
handling it such that pm states are not lost or over-written in
the process.

Some low priority event rings operate on a fast forwarding
mechanism where only the latest event is processed and the rest
are skipped. The recycle API only handles updating the
context write pointer in sequence which causes an out of bounds
doorbell issued to the device due to mismatched values. Add
another API to support handling updates for context write
pointer separately with the fast forwarding use case.

Upon external soc power down mhi controller context pointer
is set to NULL. If debugfs query is issued at that time it
results into NULL pointer dereference. Fix the issue by adding
a NULL check in debugfs show callback for event and channel.

If time sync is requested by user space when endpoint is shutting
down dev_wake count gets incremented. This is causing assert when
shutdown API checks the dev_wake count and it is still non-zero.
Fix this issue by protecting time sync API and removal of time sync
under tsync_mutex. This helps to take care of a race condition when
time sync is requested while time sync remove in progress and also
makes sure that dev_wake count becomes zero when time sync remove
is done to prevent assert condition.

If extcon handler is present and dpdm regulator is absent, current
code starts USB state machine without checking usb role switch status.
This results into USB PHY being reset while ADSP firmware is performing
charger detection. This may result into wrong/invalid charger detection
instead of SDP causing no USB enumeration. Fix this issue by checking
usb role switch status before kicking USB state machine.
