x86/mm: Remove the unused mk_kernel_pgd() #define
AFAICS the last uses of directly 'making' kernel PGDs was removed 7 years ago:
8b78c21d72d9: ("x86, 64bit, mm: hibernate use generic mapping_init")
Where the explicit PGD walking loop was replaced with kernel_ident_mapping_init()
calls. This was then (unnecessarily) carried over through the 5-level paging conversion.
Also clean up the 'level' comments a bit, to convey the original, meanwhile somewhat
bit-rotten notion, that these are empty comment blocks with no methods to handle any
of the levels except the PTE level.
