cx88: Make card database more memory efficient
From: Trent Piepho <xyzzy@speakeasy.org>
The vmux setting is only two bits, but was taking up a whole 32 in the input
description struct. By changing it to a two-bit bitfield, it can fit in what
was padding space before and drop the input size by 4 bytes, from 28 to 24.
This drops the board description struct, which has 9 inputs, from 280 to 244
bytes. Total driver size decreases by 2108 bytes.
