arm64: Correct type for PUD macros



The PUD macros (PUD_TABLE_BIT, PUD_TYPE_MASK, PUD_TYPE_SECT) use the
pgdval_t even when pudval_t is available. Even though the underlying
type for both (u64) is the same it is confusing and may lead to issues
in the future.

Fix this by using pudval_t to define the PUD_* macros.

Fixes: 206a2a73 ("arm64: mm: Create gigabyte kernel logical mappings where possible")
