gpio: nomadik: don't print out global GPIO numbers in debugfs callbacks
In order to further limit the number of references to the GPIO base number stored in struct gpio_chip, replace the global GPIO numbers in the output of debugfs callbacks by hardware offsets.

been acked by the I2C maintainer (in this case me). So, please don't pull this in via the net tree. The question raised here (extending SMBus calls to 255 byte) is complicated because we need ABI backwards compatibility.

All messages between nodes are sent as SMBus Block Writes. Each I2C bus to be used for MCTP is flagged in devicetree by a 'mctp-controller' property on the bus node. Each flagged bus gets a mctpi2cX net device created based on the bus number. A 'mctp-i2c-controller' I2C client needs to be added under the adapter. In an I2C mux situation the mctp-i2c-controller node must be attached only to the root I2C bus. The I2C client will handle incoming I2C slave block write data for subordinate busses as well as its own bus. In configurations without devicetree a driver instance can be attached to a bus using the I2C slave new_device mechanism. The MCTP core will hold/release the MCTP I2C device while responses are pending (a 6 second timeout or once a socket is closed, response received etc). While held the MCTP I2C driver will lock the I2C bus so that the correct I2C mux remains selected while responses are received. (Ideally we would just lock the mux to keep the current bus selected for the response rather than a full I2C bus lock, but that isn't exposed in the I2C mux API) This driver requires I2C adapters that allow 255 byte transfers (SMBus 3.0) as the specification requires a minimum MTU of 68 bytes.
