ASoC: msm8x16-wcd: make default spkr_ocp hold enable

Currently, OCP hold is set to zero by default which is
preventing the PA from holding the shutdown state.
Set this bit to enable OCP hold by default. Once hold is set
PA would shut down immediately during overcurrent and hold
that state unless SPKR_PA_EN bit is toggled.
