Philippe De Swert baef653a50 usb: musb: remove generic_interrupt
This patch is based on the discussion of a previous patch to fix an issue
where the omap2430 musb driver is not working for N9/N950.

Moving all the interrupt handling to the devices. Avoids inclusion of generic
interrupt and breakage due to sometimes misleading CONFIG options. This makes
sure usb always works if on of the subdrivers is chosen. Tested on Nokia N9/N950.

Partially clean up CONFIG_SOC_OMAP3430 which is not necessary in the cases
where I removed it. Also helps with the removal work of those options that
Tony Lindgren predicted would happen at some point.

Bob Liu 9c668079c8 usb: musb: hsdma: change back to use musb_read/writew
Blackfin platform doesn't support 32bits musbdma registers, so change back to
use musb_read/writew instead of musb_read/writel and simply some format casts.

Tony Lindgren 59b479e098 omap: Start using CONFIG_SOC_OMAP
We want to have just CONFIG_ARCH_OMAP2, 3 and 4. The rest
are nowadays just subcategories of these.

Search and replace the following:

ARCH_OMAP2420		SOC_OMAP2420
ARCH_OMAP2430		SOC_OMAP2430
ARCH_OMAP3430		SOC_OMAP3430

No functional changes.
