powerpc: Don't include lppaca.h in paca.h

[ Upstream commit 1aa000667669fa855853decbb1c69e974d8ff716 ]

By adding a forward declaration for struct lppaca we can untangle paca.h
and lppaca.h. Also move get_lppaca() into lppaca.h for consistency.

Add includes of lppaca.h to some files that need it.
