arm64: hugetlb: Register hugepages during arch init
Add hstate for each supported hugepage size using arch initcall.
* no hugepage parameters
Without hugepage parameters, only a default hugepage size is
available for dynamic allocation. It's different, for example, from
x86_64 and sparc64 where all supported hugepage sizes are available.
* only default_hugepagesz= is specified and set not to HPAGE_SIZE
In spite of the fact that default_hugepagesz= is set to a valid
hugepage size, it's treated as unsupported and reverted to
HPAGE_SIZE. Such behaviour is also different from x86_64 and
sparc64.
