Since the dawn of time we had CONFIG_MMC?_CD_PIN defines for each
Allwinner board, which held the name for the respective MMC card
detect GPIO. These days we don't use that in U-Boot proper anymore
(and rely on DT for that, instead), so it's just for the SPL loading.
However the card detect is actually not needed there:
- We continue loading from the same boot media that the BootROM booted
us from, so when we get to load from MMC, there is surely a card in
the slot.
- The BROM already spoiled all efforts by unconditionally accessing the
MMC bus, regardless of any card presence or not. We can't do more harm
by doing the same.
This series removes the code checking the CD pin, and also the definition
from Kconfig and all defconfigs. On top there is a cleanup for the MMC
driver, which explains the reason for still also implementing the legacy
MMC interface.
Please have a look and test!
Thanks,
Andre

The sunxi MMC code does not use the DM in the SPL, as we don't have a
device tree available that early, also no space for it.
This also means we cannot access the card-detect GPIO information from
there, so we have Kconfig symbols called CONFIG_MMCx_CD_PIN, which each
board has to define. This is a burden, also requires extra GPIO code in
the SPL.
As the SPL is the natural successor of the BootROM (from which we are
loaded), we can actually ignore the CD pin completely, as this is what
the BootROM does as well: CD GPIOs are board specific, but the BootROM
is not, so accesses the MMC devices anyway.
Remove the card detect code from the non-DM implementation of the sunxi
MMC driver, to get rid of this unneeded code.

As the SPL code for sunxi boards does not use the driver model, we have
two mmc_ops structures, one for DM, one for non-DM. The actual hardware
access code is shared, with the respective callback functions using that
common code.
To make this more obvious and easier to read, reorder the functions to
group them: we first have the common code, then the non-DM bits, and
the proper DM implementation at the end.
Also document this structure in the comment at the beginning of the file.
No functional change intended.

For legacy reasons we were defining the card detect GPIO for all sunxi
boards in each board's defconfig.
There is actually no need for a card-detect check in the SPL code (which
consequently has been removed already), and also in U-Boot proper we
have DM code to query the CD GPIO name from the device tree.
That means we don't have any user of that information left, so can
remove the definitions from the defconfigs.

Hi Andre,
Thanks for helping to get rid of sunxi_name_to_gpio().

The card detection logic is useless for an even simpler reason: because
of our spl_boot_device() implementation, SPL only accesses the MMC
interface where SPL itself was originally read from. Therefore, it must
have a card inserted.
