i2c: delete non-required instances of include <linux/init.h>
None of these files are actually using any __init type directives
and hence don't need to include <linux/init.h>. Most are just a
left over from __devinit and __cpuinit removal, or simply due to
code getting copied from one driver to the next.

i2c: Remove unneeded xxx_set_drvdata(..., NULL) calls
There is simply no reason to be manually setting the private driver
data to NULL in the remove/fail to probe cases. This is just extra
cruft code that can be removed.
A few notes:
* Nothing relies on drvdata being set to NULL.
* The __device_release_driver() function eventually calls
dev_set_drvdata(dev, NULL) anyway, so there's no need to do it
twice.
* I verified that there were no cases where xxx_get_drvdata() was
being called in these drivers and checking for / relying on the NULL
return value.
This could be cleaned up kernel-wide but for now just take the baby
step and remove from the i2c subsystem.

i2c-au1550: increase timeout waiting for master done
Double the timeout in the loop which busy-waits for the "master-done"
bit to be set. This bit indicates whether an i2c transaction has
completed; on the DB1300 and DB1550 boards this timeout is slightly
too short and causes transactions to the WM8731 codec to be falsely flagged
as failed. The timeout itself is necessary since transactions to
non-existant slaves never set this bit in the first place (and cause
i2cdetect to hang).
With this change the WM8731 codec on the DB1300/DB1550 boards is correctly
detected and initialized.

i2c: Use resource_size macro
This replace all instances in the i2c busses tree of
res->end - res->start + 1 with the handy macro resource_size(res)
from ioport.h (coming in from platform_device.h).
This was created with a simple
sed -i -e 's/\([a-z]*\)->end *- *[a-z]*->start *+ *1/resource_size(\1)/g'
Then manually replacing the PXA redefiniton of the same kind
of macro manually. Recompiled some ARM defconfigs I could find to
make a rough test so it shouldn't break anything, though I
couldn't see exactly which configs you need for all the drivers.

[MIPS] Alchemy: SMBus resource fix
The Alchemy platform code registers the SMBus device using the virtual
address of its registers instead of the physical one -- fix this, taking
into account that actually the whole megabyte is decoded by any of the
programmable serial controllers (one of which is SMBus), and that all the
Alchemy peripherals are directly mappable into KSEG1 kernel space and
therefore ioremap() call would just boil down to CKSEG1ADDR() invocation.

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.

Fix a "mis-used register" problem on the AMD MIPS Alchemy au1550
I2C interface.
In summary, the programmable serial controller seems to hang the kernel
when I send a single 'address' byte on the I2C bus. The patch
essentially uses the PSC_SMBSTAT register's TE (transmit FIFO empty)
bit to check when the transmit FIFO is empty, instead of using the
PSC_SMBEVNT register's TU (transmit underflow) bit. Using the TE bit
fixed the hang problem.
