The audio driver should not use a hardwired gpio number
from the header. Change it to use a lookup table.

This looks wrong. The n in nDET in the end of the name of the GPIO line
means active low does it not?

What I usually do when I see this is to properly set it to
GPIO_ACTIVE_LOW in the descriptor table, then invert the logic
where it's getting used.

Also rename to earphone-det instead of -ndet

+                           "hp-driver", GPIO_ACTIVE_HIGH),
+               GPIO_LOOKUP("gpio-pxa", GPIO107_HX4700_SPK_nSD,
+                           "spk-nsd", GPIO_ACTIVE_HIGH),

Same here. Rename spk-sd
