tsutsui b80737e133 Increase VM_KERNEL_PT_PAGES from 2 to 4 for x68k.
X68030 with 8MB or 12MB RAM (which is default for most X68030s)
now gets "pmap_enter_ptpage: can't get KPT page" panic again
with VM_KERNEL_PT_PAGES=2 while it works with >=14MB.
3 is enough to boot for now, but I also add a spare.

I guess this is because the post netbsd-6 vmem(9) bootstrap
changes require more kernel memory before MD pmap_init().

Note1:	netbsd-6 (which also pulls physmem detection changes
	that affect nptpages) doesn't have this problem.
Note2:	other hp300 pmap based m68k ports might have the same issue,
	but at least 12MB luna68k works with VM_KERNEL_PT_PAGES=2
	so I think it depends on kernel size and/or iomapsize.
