Ravi Bangoria 4441eb0233 powerpc/watchpoint: Fix handling of vector instructions 
Vector load/store instructions are special because they are always
aligned. Thus unaligned EA needs to be aligned down before comparing
it with watch ranges. Otherwise we might consider valid event as
invalid.

Fixes: 74c6881019 ("powerpc/watchpoint: Prepare handler to handle more than one watchpoint")
