Fix the alternate time base the same way as the default timebase. SPR_ATBL
should return a 64-bit value on 64 bit implementations.
Signed-off-by: NAurelien Jarno <aurelien@aurel32.net>

On PPC we have a 64-bit time base. Usually (PPC32) this is accessed using
two separate 32 bit SPR accesses to SPR_TBU and SPR_TBL.

On PPC64 the SPR_TBL register acts as 64 bit though, so we get the full
64 bits as return value. If we only take the lower ones, fine. But Linux
wants to see all 64 bits or it breaks.

This patch makes PPC64 Linux work even after TB crossed the 32-bit boundary,
which usually happened a few seconds after bootup.

When using the escc with Linux, we need interrupts. So instead of creating
a dummy device, let's just map them to the openpic we have anyways.

This makes Linux on PPC64 with console=ttyPZ0 work.

Obviously, this change needs to be reflected in openbios. Patch for that
follows this one. Please update the binary then.

When lowering an IRQ line, we search for the line we're supposed to lower.

Usually we run into an optimization there that queues up interrupts. This
queue ends with -1. Unfortunately we didn't set the first item to -1.

This patch fixes this, making interrupts work on PPC64.
