There is an ID collision between the JV and RV families. Both chips are
very similar in practice, it is mostly a matter of electrical
differences (mostly power consumption being lower).

As a significant difference, RV chips identify themselves as supporting
The new SFDP (rev F) field which forces an alternate write SR2 opcode
(0x31).

Since they share the IDs but not the names, we must hide the names using
a fixup.
