This commit adds pin to pad mapping and output format configuration support in CX2584x-series chips to cx25840 driver. This functionality is then used to allow disabling ivtv-specific hacks (called a "generic mode"), so cx25840 driver can be used for other devices not needing them without risking compatibility problems.
