[PATCH] sh: Export sh7343 VPU and VEU using uio_pdrv_genirq

[Magnus Damm]

From: Magnus Damm <damm@igel.co.jp>

This patch exports the VPU and VEU blocks of the sh7343 to user space
using the uio_pdrv_genirq platform driver.

Signed-off-by: Magnus Damm <damm@igel.co.jp>

 Applies on top of current sh-2.6 git plus Shimoda-sans sh7343 changes.
