Audio: Check for jack status during boot time for HP_DET gpio pin only

BZ: 27809

During clv_soc_jack_add_gpio(), clv_soc_jack_gpio_detect() is
executed irrespective of GPIO pin. (Headset detection, button press)
This caused, erroneous jack status reported to above layer during
boot time.

The solution is to verify jack status during boot time for HP_DET
gpio pin only.

This patch also contains some changes in clv_machine, cs42l73 driver
to be used as a loadable module.
