This patch exports the VPU, VEU(1) and VEU(2) blocks of the sh7366
to user space using the uio_pdrv_genirq platform driver.
While at it, fix up the VEU(2) interrupt vector.

The USBF function on sh7722 is currently not working with the m66592_udc
driver. The driver is using platform_get_resource_byname() so my commit
a0d29798e568116aa6c32aef7bab2d9e620c88ad broke sh7722 support.
The long term fix is to replace platform_get_resource_byname() in the
driver with platform_get_resource(), but this helps until that happens.

Presently with preempt enabled there's the possibility to be preempted
after the TIF_USEDFPU test and the register save, leading to bogus
state post-__switch_to(). Use an explicit preempt_disable()/enable()
pair around unlazy_fpu()/clear_fpu() to avoid this. Follows the x86
change.
