Servo V3: Remap fw_wp to gpio.

fw_wp is no longer controlled via i2c rather it is now a gpio: gpio2_2.

However gpio2_2 is not properly labelled in the omap_muxes. So it's
muxfile needs to be hard-coded rather than found automatically. This
change allows muxfile to be properly piped into the gpio wr_rd function.

TEST=dut-control with link at desk. FAFT test failed before to set fw_wp
and now the test works and passes.
