uaccess: unify inline vs outline copy_{from,to}_user() selection
The kernel allows arches to select between inline and outline
implementations of the copy_{from,to}_user() by defining individual
INLINE_COPY_FROM_USER and INLINE_COPY_TO_USER, correspondingly. However,
all arches enable or disable them always together.
Without the real use-case for one helper being inlined while the other
outlined, having independent controls is excessive and error prone.
Switch the codebase to the single unified INLINE_COPY_USER control.
