Subject: [dpdk-dev] [PATCH v3 1/2] net/ice: factorize firmware loading

Both "normal" and "dcf" inits have their copy of some firmware loading
code.

The DSN query is moved in specific parts for the "normal" and "dcf" init.

A common helper ice_load_pkg is then introduced and takes an adapter
pointer as its main input.

This helper takes care of finding the right firmware file and loading
it.
The adapter active_pkg_type field is set by this helper.

The ice_access macro is removed from the osdep.h header: osdep.h should
only hosts wrappers for base driver code.

I'm wondering what's full name for ice firmware in F34, has any *.xz
postfix ? If so, the search method will also needs to be updated, since
we will check each file can be accessed: 

#define ICE_PKG_FILE_DEFAULT "/lib/firmware/intel/ice/ddp/ice.pkg"
#define ICE_PKG_FILE_UPDATES "/lib/firmware/updates/intel/ice/ddp/ice.pkg"
