kvm-all: Align to qemu_real_host_page_size in kvm_set_phys_mem
As the comment in kvm_set_phys_mem() says, KVM works in page size chunks. However it uses hardcoded TARGET_PAGE_SIZE which is 4K on most platforms while actual host may use different page size, for example, PPC64 hosts use 64K system pages. This replaces static TARGET_PAGE_SIZE with run-time calculated qemu_real_host_page_size.
