Driver probe routine allocates structure to communicate status
and parameters between functions in the driver. Also call
load_ifs_binary() to load the scan image file.
There is a separate scan image file for each processor family,
model, stepping combination. This is read from the static path:
/lib/firmware/intel/ifs/{ff-mm-ss}.scan
Step 1 in loading is to generate the correct path and use
request_firmware_direct() to load into memory.
Subsequent patches will use the IFS MSR interfaces to copy
the image to BIOS reserved memory and validate the SHA256
checksums.
