pcmcia: deprecate CS_NO_MORE_ITEMS
CS_NO_MORE_ITEMS is returned by the CIS tuple reading and parsing code if the end of a tuple chain is reached. As at least one PCMCIA driver relies on matching this return value, replace it with -ENOSPC which is now uniquely used for this purpose within the in-kernel pcmcia subsystem.
