Davinci: eliminate pinmux offset verbosity
Pinmux registers are sequential, and do not need to be enumerated out as they currently are. This reduces code volume and keeps things simple. If some future SoC comes up with a discontiguous register map, PINMUX() can then be expanded with local token pasting.
