bc15cde0c4 i2c: Don't check return value from i2c_recv() 
i2c_recv() cannot fail, so there is no need to check the return
value.  It also returns unt8_t, so comparing with < 0 is not
meaningful.

Fix up various I2C controllers to remove the unneeded code.

643bb6fca7 arm: Uniquely name imx25 I2C buses. 
The imx25 chip provides 3 i2c buses, but they have all been named
"i2c", which makes it difficult to predict which bus a device will
be connected to when specified on the command line.

This patch addresses the issue by naming the buses uniquely:
  i2c-bus.0 i2c-bus.1 i2c-bus.2

Move the inclusion out of hw/hw.h, most files do not need it.

3afcbb01bc i.MX: Standardize i.MX I2C debug 
The goal is to have debug code always compiled during build.

We standardize all debug output on the following format:

[QOM_TYPE_NAME]reporting_function: debug message

The qemu_log_mask() output is following the same format as
the above debug.
