hexagon: Use raw_copy_to_user 



Commit ac4691fa ("hexagon: switch to RAW_COPY_USER") replaced
__copy_to_user_hexagon() with raw_copy_to_user(), but did not catch
all callers, resulting in the following build error.

arch/hexagon/mm/uaccess.c: In function '__clear_user_hexagon':
arch/hexagon/mm/uaccess.c:40:3: error:
	implicit declaration of function '__copy_to_user_hexagon'
