I'd much rather we change from having the TYPE_ ebnum and move th
a bitfield specificying the capabilities of the hardware, so that if
in the future we don't have an S3C64XX_ADCCLRINTPNDNUP we don't need to
go and change the if () around it for the new driver.
I used feat and FEAT_ as a reasonable contraction for feature and features
to avoid typing whilst still conveying the meaning of the flags.
