i2c-bfin-twi: Register adapter with a specific bus number
All the users of this driver explicitly specify the I2C bus numbers
to be used in their platform data. Make the driver respect that.

i2c-au1550: properly terminate zero-byte transfers
Zero-bytes transfers would leave the bus transaction unfinished
(no i2c stop is sent), with the following transfer actually
sending the slave address to the previously addressed device,
resulting in weird device failures (e.g. reset minute register
values in my RTC).
This patch instructs the controller to send an I2C STOP right after
the slave address in case of a zero-byte transfer.

mpc-i2c: Propagate error values properly
Propagate the error values returned by i2c_wait() instead of overriding
them with a meaningless -1.

i2c: Add i2c_new_dummy() utility
This adds a i2c_new_dummy() primitive to help work with devices
that consume multiple addresses, which include many I2C eeproms
and at least one RTC.

i2c: Drop legacy locking in i2c_new_probed_device
