The size of the Problem State Priority Boost Register is only
32 bits, but the kvm_vcpu_arch->pspb variable is declared as
"ulong", ie. 64-bit. However, the assembler code accesses this
variable with 32-bit accesses, and the KVM_REG_PPC_PSPB macro
is defined with SIZE_U32, too, so that the current code is
broken on big endian hosts: kvmppc_get_one_reg_hv() will only
return zero for this register since it is using the wrong half
of the pspb variable. Let's fix this problem by adjusting the
size of the pspb field in the kvm_vcpu_arch structure.
