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 v1:
 - platform_get_irq now works for sparc, so that is used for all platforms
 - Acks by Peter Korsgaard [off-list ref]
