arm64/mm: export contpte symbols only to GPL users

Patch series "Address some contpte nits".

These 2 patches address some nits raised by Catalin late in the review cycle for
my contpte series [1].

This patch (of 2):

The contpte symbols must be exported since some of the public inline
ptep_* APIs are called from modules and these inlines now call the contpte
functions.  Originally they were exported as EXPORT_SYMBOL() for fear of
breaking out-of-tree modules.  But we subsequently concluded that
EXPORT_SYMBOL_GPL() should be safe since these functions are deeply core
mm routines, and any module operating at this level is not going to be
able to survive on EXPORT_SYMBOL alone.
