These bits adjust the sensitivity of the right channel
headphone short detector in 25mA steps.This trip point can
vary by ~30% over process so leave plenty of guardband to
avoid false trips. This short detect trip point is also effected by
the bias current adjustments made by CHIP_REF_CTRL ->
BIAS_CTRL and by CHIP_ANA_TEST1 -> HP_IALL_ADJ.
