The constants are 64bit but not explicitly declared UL resulting
in sparse warnings. Fixed by declaring the constants UL.

most of the warnings are local constants in book3s_hv.c, PSSCR_GUEST_VIS
from reg.h is not. Although PSSCR_GUEST_VIS is not #ifdef CONFIG_PPC_BOOK3S
it seems only to be used in that particular platform (check with cscope).
The constants fit in the target variables so the size declaration
discrepancy does not actually cause a problem here.
Patch was compiletested with: ppc64_defconfig (implies
CONFIG_KVM=y, CONFIG_KVM_BOOK3S_64_HV=m)
Patch is against 4.18-rc3 (localversion-next is next-20180705)
