Fix smartpqi arcconf parsing for mixed SSD/HDD arrays with 4K block sizes

[andaaron]

1. Handle "4K Bytes" and other SI-suffixed block size tokens that caused strconv.Atoi failures on newer hardware.
2. Split multiple logical devices within a single arcconf output chunk.
3. Map new InterfaceType variants ("SATA SSD", "SAS 4K").
4. Parse Channel and Protocol from physical device output.
5. Fix GetDiskType returning HDD for the first non-matching drive.

Thanks for adding some additional support and with tests!

I left some minor items; I think mostly around the parseBlockSize; I'd like to simplify and make it clear we're looking at the Disk "geometry" or "sector size" or "native block"; rather than anything related to capacity of a disk.

Please take a look.

Thanks for updating the parseBlockSize. I'm +1 once squashed and CI passes.

@raharper, I have fixed the issue, please run CI again.
