powerpc: Remove direct call to mmap2 syscall handlers
Syscall handlers should not be invoked internally by their symbol names,
as these symbols defined by the architecture-defined SYSCALL_DEFINE
macro. Move the compatibility syscall definition for mmap2 to
syscalls.c, so that all mmap implementations can share a helper function.
Remove 'inline' on static mmap helper.
