[INF] Add support for the NEC Star Alpha C-bus bridge device (#8446)

This device is present in some PC-98 models without C-bus slots
and has a SubClass ID of 0x80 (other bridge) instead of 0x01 (ISA bridge),
thus a critical device database entry is required.

00:06.0 Bridge [0680]: NEC Corporation Star Alpha 2 [1033:002c] (rev 01)
Subsystem: Unknown [0000:0000]
Flags: bus master, medium devsel, latency 0

Addendum to commit 84fabd819dcc7130f26d6e7bccee84f72e191d78.
