There are a number of places in the arch code that read a pte by using the
READ_ONCE() macro. Refactor these call sites to instead use the
ptep_get() helper, which itself is a READ_ONCE(). Generated code should
be the same.
This will benefit us when we shortly introduce the transparent contpte
support. In this case, ptep_get() will become more complex so we now have
all the code abstracted through it.
