PPC: Redesign interrupt trigger path
According to the Book3S spec, the interrupt context starts with an MSR
value that is rather simple. If we leave out the HV case, it's almost
always 0.
To reflect this, let's redesign the way that MSR value gets calculated.
Using this, we also squash the bug where MSR_POW can slip through into
the interrupt handler MSR.

Title:
Regression in booting HelenOS/ppc under Qemu
Status in Home for various HelenOS development branches:
New
Status in QEMU:
New
Bug description:
Mark Cave-Ayland identified Qemu commit
41557447d30eeb944e42069513df13585f5e6c7f as the first bad commit which
prevents HelenOS/ppc from booting with OpenBIOS taken from Qemu
0.11.1. Note that we deliberately use the OpenBIOS from Qemu 0.11.1
because there is another suspected, unrelated bug in newer versions of
OpenBIOS.
For reproducing purposes, the following HelenOS image can be used
(latest HelenOS exhibits the same behavior):
http://www.helenos.org/releases/HelenOS-0.4.2-ppc32.iso
Commit 41557447d30eeb944e42069513df13585f5e6c7f will result in HelenOS
not making any further progress after it prints "init: Spawning
/srv/devfs".
The previous commit, f844c817d726cd2bdb431aa41c8217891ede2eaf, works
fine - HelenOS will spawn a couple of shell instances and will be
accepting user input.
