[PATCH] USB: pxa27x OHCI - Separate platform code from main driver
To allow multiple platforms to use the PXA27x OHCI driver, the platform
code needs to be moved into the board specific files in
arch/arm/mach-pxa. This patch does this for mainstone and adds
preliminary hooks to allow other boards to use the driver.
This has been compile tested for mainstone and successfully run on Spitz
(Sharp Zaurus SL-C3000) with the addition of an appropriate board
support file.
