[PATCH v1 3/8] powerpc/uaccess: Move copy_mc_xxx() functions down

[Christophe Leroy <christophe.leroy@csgroup.eu>]

copy_mc_xxx() functions are in the middle of raw_copy functions.

For clarity, move them out of the raw_copy functions block.

They are using access_ok, so they need to be after the general
functions in order to eventually allow the inclusion of
asm-generic/uaccess.h in some future.
