pseries: Implement hcall-bulk hypervisor interface
This patch adds support for the H_REMOVE_BULK hypercall on the pseries machine. Strictly speaking this isn't necessarym since the kernel will only attempt to use this if hcall-bulk is advertised in the device tree, which previously it was not. Adding this support may give a marginal performance increase, but more importantly it reduces the differences between the emulated machine and an existing PowerVM or kvm system, both of which already implement hcall-bulk.
