Add functionality for accessing device hardware registers, loading
firmware bundles, and accessing the device's internal flash memory,
and use it to implement the devlink flash functionality.

Patch breakdown:
Patch1: helpers to access hardware registers
Patch2: low level functions to access flash memory
Patch3: support to load firmware bundles
Patch4: refactoring device initialization and helper functions
for stopping and resuming device normal operation
Patch5: devlink .flash_update callback implementation

Changes:
v4:
* fixed issues reported by Jakub (see patches' changelogs)
v3:
* fixed issues reported by Przemek (see patches' changelogs)

in general you should carry tags added in previous revisions,
especially if there were no big/opposing/controversial changes
anyway, for the series:

v2:
* fixed several warnings found by patchwork bot
* added includes into new .c files
