PCI: Deprecate pcim_iomap_table(), pcim_iomap_regions_request_all()

Deprecate pcim_iomap_table().  It returns a pointer to a table of
ioremapped BARs, or NULL if it fails.  This makes uses like this:

  addr = pcim_iomap_table(pdev)[0];

problematic because it causes a NULL pointer dereference on failure.
Callers should use pcim_iomap() instead.

Deprecate pcim_iomap_regions_request_all() because it is built on
__pci_request_region() and is managed if pcim_enable_device() has been
called, but unmanaged otherwise, which is prone to errors.

Callers should either use pcim_iomap_regions() to request and map BARs, or
use pcim_request_region() followed by pcim_iomap().
