Zeroing ITR shouldn't ack irq zero.

Fix PWT & PWL clocks, fix user refcounting for clocks, add 'hsab_ck' and 'usb_w2fc_ck'.
Fix TCMI register addresses.
Implement OMAP McBSP controller and connection to I2S-compatible CODECs.
Add audio support for TSC2102 as an I2S CODEC.
Connect TSC2102 I2S interface to CPU's McBSP1 interface in the Palm Tungsten|E.
Correct '>' instead of '>>' typos.
Implement GPIO PIN_CONTROL register (not in OMAP310 TRM, from OMAP1510).
