Revert "debug code added for bma180 and forced polling mode"
this also removes a debugging printk from bq27000 driver
and re-enables our DTR extension for omap-serial.c

With this we are closer to linus/master

This reverts commit 9ac72d37b538dc2b9a6f1eaca6c7ce657c93aba0.

Sound: made sound (temporarily) configured to be compiled into the kernel
