i2c: mxs: only flag completion when queue is completely done
The hardware generates an interrupt for every completed command in the
queue while the code assumed that it will only generate one interrupt
when the queue is empty. So, explicitly check if the queue is really
empty. This patch fixed problems which occurred due to high traffic on
the bus. While we are here, move the completion-initialization after the
parameter error checking.

i2c-mxs: set controller to pio queue mode after reset
mxs_reset_block() clears the PIO_QUEUE_MODE bit. So we have
to set it again after a controller reset.

i2c: add driver for Freescale i.MX28
Currently only supporting the PIOQUEUE-mode, because DMA-support for
this platform is not yet in mainline. When it becomes available and
support has been added to this driver, it will also be suitable for
i.MX23 and STMP3xxx.
