sw64: add arch_hugetlb_valid_size for C4 

Sunway inclusion
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/IB73UR



--------------------------------

Add arch_hugetlb_valid_size routine used to validate passed huge page
size.

Remove hugepagesz= command line parsing which has been moved into an
arch independent routine.
