> The ice_devlink_flash_update function performs a few upfront checks and
> then calls ice_flash_pldm_image.
> 
> Most of these checks actually make more sense within the context of
> ice_flash_pldm_image. Refactor this function to fit the argument format of
> the .flash_update devlink handler, and merge the checks from
> ice_devlink_flash_update.
> 
> Note that the check for overwrite mask was converted to a switch because it
> made the check easier to read by avoiding the massively long line or weird
> line breaks that were hard for my eyes to follow.
> 
> When moving the ice_cancel_pending_update function, notice that it also
> takes the NVM semaphore. The main flash update process also requires the
> NVM hardware semaphore. We can eliminate the call to get the semaphore
> from ice_cancel_pending_update by placing the check after we acquire the
> semaphore during ice_flash_pldm_image.
> 
> With this change, the ice_flash_pldm_image becomes the main entry point
> for the devlink flash update, eliminating some unnecessary boiler plate code.
> This also eases supporting a dry run with the PLDM library in a future change.
