parisc: Replace PT_NLEVELS with CONFIG_PGTABLE_LEVELS
The following warning is seen when compiling parisc images
./arch/parisc/include/asm/pgalloc.h: In function 'pgd_alloc':
./arch/parisc/include/asm/pgalloc.h:29:5: warning: "PT_NLEVELS" is not defined
Some definitions of PT_NLEVELS were missed with the conversion to
CONFIG_PGTABLE_LEVELS.
Fixes: f24ffde432
("parisc: expose number of page table levels
on Kconfig level")
