V4L/DVB (6019): cx88: Make card database more memory efficient
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.
