powerpc: Make the decr interrupt type overridable

Make it possible for boards to override the kind of interrupt
to be signaled when the decr timer hits. The 405's signal PIT
interrupts while the 440's signal DECR.

KVM: PPC: Add level based interrupt logic

KVM on PowerPC used to have completely broken interrupt logic. Usually,
interrupts work by having a PIC that pulls a line up/down, so the CPU knows
that an interrupt is active. This line stays active until some action is...

PPC: Make DCR uint32_t

For what I know DCR is always 32 bits wide, so we should also use uint32_t to
pass it along the stacks.

This fixes a warning when compiling qemu-system-ppc64 with KVM enabled, making
it compile without --disable-werror

PPC64: Fix alternate timebase

PPC64: Fix timebase

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...
