Since 43cc71ee, the platform
modalias is prefixed with "platform:". Add MODULE_ALIAS() to the
hotpluggable I2C platform drivers, to allow module auto loading.

Blackfin TWI controller hardware pin should be requested from GPIO port controller
Before BF54x, there is no need to do this. But as long as BF54x and BF52x
are supported by this generic driver, the missing pin mux operation should be
added.

 - Dynamic alloc the resource of TWI driver data according to board information
 - TWI register read/write accessor based on dynamic regs_base
 - Support TWI0/TWI1 for BF54x

All the users of this driver explicitly specify the I2C bus numbers
to be used in their platform data. Make the driver respect that.

Remove this unneeded mutex. Indeed it was used to serialize access to
the hardware, but this is already done by the i2c-core layer, see
'bus_lock' mutex used by i2c_transfer().
