target/ppc: Change MSR_* to follow POWER ISA numbering convention
Today we have the issue where MSR_* values are the 'inverted order'
bit numbers from what the ISA specifies. e.g. MSR_LE is bit 63 but
is defined as 0 in QEMU.
Add a macro to be used to convert from QEMU order to ISA order.
This solution requires less changes than to use the already defined
PPC_BIT macro, which would turn MSR_* in masks instead of the numbers
itself.
