[PATCHv6 1/5] iomap: Rename iomap_page_create/release() to iomap_iop_alloc/free()

["Ritesh Harjani (IBM)" <ritesh.list@xxxxxxxxx>]

This patch renames the iomap_page_create/release() functions to
iomap_iop_alloc/free() calls. Later patches adds more functions for
handling iop structure with iomap_iop_** naming conventions.
Hence iomap_iop_alloc/free() makes more sense to be consistent with all
APIs.
