cxl: Remove unnecessary cxl_pci_window_alignment()

cxl_pci_window_alignment() is referenced only via the struct
pci_controller_ops.window_alignment function pointer, and only in the
powerpc implementation of pcibios_window_alignment().

pcibios_window_alignment() defaults to returning 1 if the function pointer
is NULL, which is the same was what cxl_pci_window_alignment() does.

cxl_pci_window_alignment() is unnecessary, so remove it.  No functional
change intended.
