On sparc, irqs are not present as an IORESOURCE in the struct platform_device
representation. By using platform_get_irq instead of platform_get_resource the
driver works for sparc.
The GRLIB port of the ocores i2c controller needs custom getreg and setreg
functions to allow for big endian register access and to deal with the fact that
the PRELOW and PREHIGH registers have been merged into one register.

Changes since v2:
- Return error from platform_get_irq on error
- Trigger usage of the grlib specific functions on compatible property instead
of name
Andreas Larsson (2):
i2c: i2c-ocores: Add irq support for sparc
i2c: i2c-ocores: Add support for the GRLIB port of the controller and
custom getreg and setreg functions
