Support Raspberry Pi 2 with MoOde 9

[Tim Curtis]

I just tested a different old Raspberry Pi (Model A Rev 2).

Code:

cat /proc/cpuinfo | awk -F': ' '/Revision/ {print $2}'
0008

Code:

# Without 0x17 mask it works
/var/www/util/pirev.py 

0x8    A    2.0    256MB    Sony UK    ?

Code:

# With 0x17 mask the script even crashes, as 0x08 'and'-combined with 0x17 becomes to non existing revison code 0X00.

/var/www/util/pirev.py
Traceback (most recent call last):
 File "/var/www/util/pirev.py", line 185, in <module>
   main()
 File "/var/www/util/pirev.py", line 165, in main
   rev_info = decode_new_style_code(code)
 File "/var/www/util/pirev.py", line 133, in decode_new_style_code
   old_rev = OLD_REVISION_CODES[code&0x17]
KeyError: 0

Thanks for fixing.

It's fixed for upcoming 9.1.0
