KVM: PPC: Book3S HV: simplify kvm_cma_reserve()

Patch series "memblock: seasonal cleaning^w cleanup", v3.

These patches simplify several uses of memblock iterators and hide some of
the memblock implementation details from the rest of the system.

This patch (of 17):

The memory size calculation in kvm_cma_reserve() traverses memblock.memory
rather than simply call memblock_phys_mem_size().  The comment in that
function suggests that at some point there should have been call to
memblock_analyze() before memblock_phys_mem_size() could be used.  As of
now, there is no memblock_analyze() at all and memblock_phys_mem_size()
can be used as soon as cold-plug memory is registered with memblock.

Replace loop over memblock.memory with a call to memblock_phys_mem_size().
