ppc/xive2: Support crowd-matching when looking for target
XIVE crowd sizes are encoded into a 2-bit field as follows: 0: 0b00 2: 0b01 4: 0b10 16: 0b11 A crowd size of 8 is not supported. If an END is defined with the 'crowd' bit set, then a target can be running on different blocks. It means that some bits from the block VP are masked when looking for a match. It is similar to groups, but on the block instead of the VP index. Most of the changes are due to passing the extra argument 'crowd' all the way to the function checking for matches.
