Fixing XBUS PG lookup to mark both E44D and E55D as valid entries
Currently, there are two version of the MVPD PG keyword:
- E44D == XBUS0 bad
- E45D and E55D == XBUS0 and 2 bad
Spec indicates that both iox (second nibble) and pbiox
(third nibble) are bad for sforza and monza type modules.
We support generically the following cases:
- 0xE50D --> xbus chiplet good
- 0xE40D --> xbus chiplet good
and rely solely on the pbiox as the Xbus target indicator
(0x0040, 0x0020, 0x0010) for all types of chips.
