ASoC: Tegra: WAR to avoid incorrect mic detection event
When 3-pin pin is interted in cardhu headset port mic short interrupts
get asserted which also triggers mic detection interrupt. As a result
ALSA detects presence of mic mistakenly. For cardhu register WM8903
mic short event for mic detection so that mic detection interrupt
generated during mic short event gets cancelled.
