My previous comment about using binary constants still stands. Please
either address review comments or reply at least. Ignoring reviews is not
an option.
Aside of that I really have to ask about the naming of these constants. Are
these names hardware register nomenclature? If yes, they are disgusting. If
no, they are still disgusting, but should be changed to sensible ones,
which just match the IRQ_TYPE naming convention.
PDC_LEVEL_LOW = 000b,
PDC_EDGE_FALLING = 010b,
....
Checkpatch doesn't like binary constants. I guess I will need to keep
the enum definitions in hex or decimal. I will remove the binary from
the comments though.

checkpatch: warn when using gcc's binary constant ("0b") extension
The gcc extension for binary constants that start with 0b is only
supported with gcc version 4.3 or higher.
The kernel can still be compiled with earlier versions of gcc, so have
checkpatch emit a warning for these constants.
Restructure checkpatch's constant finding code a bit to support finding
these binary constants.
