[ARM] 4403/1: Make the PXA-I2C driver work with lockdep validator
Using lockdep validator causes warnings like
INFO: trying to register non-static key.
the code is fine but needs lockdep annotation.
turning off the locking correctness validator.

This is caused by memcpy'ing a statical initialized spin-lock. This patch
removes a static pxa_i2c structure which was used only as a source for this
memcpy() operation. Instead of, members and the spinlock will be
initialized manually.
