[PATCH] arm64/mm: Change protval as 'pteval_t' in map_range()

[Anshuman Khandual]

pgprot_t has been defined as an encapsulated structure with pteval_t as its
element. Hence it is prudent to use pteval_t as the type instead of via the
size based u64. Besides pteval_t type might be different size later on with
FEAT_D128.
