The snippet of code to add a drive to our drive list needs to
get called from 2 places in the future. Split it into a separate
function.

EFI payloads can query for the device they were booted from. Because
we have a disconnect between loading binaries and running binaries,
we passed in a dummy device path so far.
Unfortunately that breaks grub2's logic to find its configuration
file from the same device it was booted from.
This patch adds logic to have the "load" command call into our efi
code to set the device path to the one we last loaded a binary from.
With this grub2 properly detects where we got booted from and can
find its configuration file, even when searching by-partition.

A EFI applications usually want to access storage devices to load data from.
This patch adds support for EFI disk interfaces. It loops through all block
storage interfaces known to U-Boot and creates an EFI object for each existing
one. EFI applications can then through these objects call U-Boot's read and
write functions.
