Split OpenPIC support into powerpc so ports only need minimal custom
...
configuration. openpic_init() now takes a single argument that is the
base of the OpenPIC register space.

provide dymmy symbol 'syscall' to make ppc kernels
...
linkable after recent emul changes - it's used in emul_netbsd and friends
XXX this is probably wrong solution; should powerpc have separate

Add an align argument to uvm_map() and some callers of that
