For I2C devices we just setting the node pointer in the archdata. This
is needed so that the I2C devices could find their OF tree nodes.

Format string bug. Not exploitable, as this is only writable by root,
but worth fixing all the same.

SPI has a similar problem as I2C in that it needs to determine an
appropriate modalias value for each device node. This patch adapts
the of_i2c of_find_i2c_driver() function to be usable by of_spi also.

If an I2C device node does not specify an interrupt, the .irq member of the
board_info struct was set to -1. This caused crashes on following
irq_dispose_mappings. Leave it NO_IRQ as returned from irq_of_parse_and_map.
(Suggesting -1 as 'i2c-no-irq' used to be a bug in linux/i2c.h.)

Change the name of the device from "rtc-ds1374" to just "ds1374", to match
what all other RTC drivers do. I seem to remember that this name was
chosen to avoid possible confusion with an older ds1374 driver, but that
driver was removed 3 months ago.

Fix build breakage introduced in commit "[POWERPC] i2c: OF helpers for
the i2c API". If i2c-core is compiled as a module, the helper needs
to be compiled as a module, as well. Rename i2c.c to of_i2c.c to
avoid name space conflict.
[paulus@samba.org: Changed dependency from OF to PPC_OF to avoid
sparc{32,64} allmodconfig breakage.]
