ev_cdev_write_pending flag is preventing a TX message post for
AT port while MBIM transfer is ongoing.
Removed the unnecessary check around control port TX transfer.

Devlink initialization flow was overwriting the IP traffic
channel configuration. This was causing wwan0 network interface
to be unusable after fw flash.
When device boots to fully functional mode restore the IP channel
configuration.

The devlink parameters are not the right mechanism to pass
extra parameters to device flashing. The params added are
also undocumented.

This patch brings-in support for M.2 7560 Device firmware flashing &
coredump collection using devlink.
- Driver Registers with Devlink framework.
- Register devlink params callback for configuring device params
required in flashing or coredump flow.
- Implements devlink ops flash_update callback that programs modem
firmware.
- Creates region & snapshot required for device coredump log collection.
On early detection of device in boot rom stage. Driver registers with
Devlink framework and establish transport channel for PSI (Primary Signed
Image) injection. Once PSI is injected to device, the device execution
stage details are read to determine whether device is in flash or
exception mode. The collected information is reported to devlink user
space application & based on this informationi, application proceeds with
either modem firmware flashing or coredump collection.
