ipq806x: extend GSBI driver to support i2c on any GSBI block
The GSBI driver is extended to be able to program the CTRL reg for any given
GSBI block. The NS and MD registers programming is made more readable by
programming the M, N, D and other bits of the registers individually.
Defined configure structs for each QUP block to be able to track the init
status for each qup.
Configured GPIO8 and GPIO9 for I2C fuction.
BRANCH=chromeos-2013.04
BUG=chrome-os-partner:36722
TEST=Booted up storm P0.2, verified that the TPM on GSBI1 still works.
