sdio: rework cis tuple parsing

Rework the current CIS tuple parsing code, reusing the existing
infrastructure and providing an easy way to add new CISTPL_FUNCE parsers
by TPLFE_TYPE.

Valid known CIS tuples are now silently queued for the SDIO function
driver when not parsed/processed (-EILSEQ) by the SDIO core.  Unknown CIS
tuples (-ENOENT) are queued too for the SDIO function driver without
aborting the initialization, but emit a warning in the kernel log.

CISTPL_FUNCE tuples can be "whitelisted" now by adding a matching entry to
the cis_tpl_funce_list table.
