sparc64: Fix lockdep issues in LDC protocol layer.

Browse source

We're calling request_irq() with a IRQs disabled.

No straightforward fix exists because we want to
enable these IRQs and setup state atomically before
getting into the IRQ handler the first time.

What happens now is that we mark the VIRQ to not be
automatically enabled by request_irq().  Then we
make explicit enable_irq() calls when we grab the
LDC channel.

This way we don't need to call request_irq() illegally
under the LDC channel lock any more.

Bump LDC version and release date.
