From: Ian Molton <ian@mnementh.co.uk>
func0 is not provided by the mmc stack as a function when probing.
Instead providing specific access functions to read/write it.
This prepares for a patch to remove the actual array entry itself.

Its more efficient to test the register we're interested in first,
potentially avoiding two more comparisons, and therefore always avoiding
one comparison per call on all other chips.

In preparation for removing the function array, remove all code that
refers to function by index and replace with pointers to the function
itself.

Guess you merged wireless-drivers/master in between. I just rebased and
resolved the conflict and sent a V2 with the remaining patches.

Actually fast forwarded to latest net-next, so I got the latest
wireless-drivers via that route.

In brcmf_sdio_buscore_read() there is some special handling upon
register access to chipid register of the chipcommon core. Add
comment explaining why it is done here.
