powerpc/kvm: Fix build error when PPC_MEM_KEYS/PPC_PSERIES=n
lkp reported a randconfig failure:
In file included from arch/powerpc/include/asm/book3s/64/pkeys.h:6,
from arch/powerpc/kvm/book3s_64_mmu_host.c:15:
arch/powerpc/include/asm/book3s/64/hash-pkey.h: In function 'hash__vmflag_to_pte_pkey_bits':
>> arch/powerpc/include/asm/book3s/64/hash-pkey.h:10:23: error: 'VM_PKEY_BIT0' undeclared
10 | return (((vm_flags & VM_PKEY_BIT0) ? H_PTE_PKEY_BIT0 : 0x0UL) |
| ^~~~~~~~~~~~
We added the include of book3s/64/pkeys.h for pte_to_hpte_pkey_bits(),
but that header on its own should only be included when PPC_MEM_KEYS=y.
Instead include linux/pkeys.h, which brings in the right definitions
when PPC_MEM_KEYS=y and also provides empty stubs when PPC_MEM_KEYS=n.
