Use MMC_CAP_ names instead of MMC_MODE_. This makes it more
clear that these are capabilities of host/card and do not refer
to the current mode. These are in line with the Linux Kernel
except for MMC_CAP_MMC_HIGHSPEED_52MHZ which could be fixed
later.

Whether the controller works in 8bit mode is not only dependent
on the controller but also on the board having wired up 8 data
lines, so put a capabilities field in platform data.
