EXT_CSD[248] includes the default maximum timeout for CMD6.
This field is added at eMMC4.5 Spec. And it can be used for default
timeout except for some operations which don't define the timeout(i.e.
background operation, sanitize, flush cache) in eMMC4.5 Spec.

There's no special reason why AMBA device drivers should not be
auto-loadable via udev, but udev currently has no way to map AMBA
device IDs to drivers.
