env: Pass additional parameters to the env lookup function
In preparation for the multiple environment support, let's introduce two
new parameters to the environment driver lookup function: the priority and
operation.
The operation parameter is meant to identify, obviously, the operation you
might want to perform on the environment.
The priority is a number passed to identify the environment priority you
want to retrieve. The lowest priority parameter (0) will be the primary
source.
Combining the two parameters allow you to support multiple environments
through different priorities, and to change those priorities between read
and writes operations.
This is especially useful to implement migration mechanisms where you want
to always use the same environment first, be it to read or write, while the
common case is more likely to use the same environment it has read from to
write it to.

cmd: nvedit: Get rid of the env lookup
The nvedit command is the only user of env_driver_lookup_default outside of
the environment code itself, and it uses it only to print the environment
it's about to save to during env save.
As we're about to rework the environment to be able to handle multiple
environment sources, we might not have an idea of what environment backend
is going to be used before trying (and possibly failing for some).
Therefore, it makes sense to remove that message and move it to the
env_save function itself. As a side effect, we also can get rid of the call
to env_driver_lookup_default that is also about to get refactored.

This patch provides
* a uclass for EFI drivers
* a EFI driver for block devices
For each EFI driver the uclass
* creates a handle
* adds the driver binding protocol
The uclass provides the bind, start, and stop entry points for the driver
binding protocol.
In bind() and stop() it checks if the controller implements the protocol
supported by the EFI driver. In the start() function it calls the bind()
function of the EFI driver. In the stop() function it destroys the child
controllers.
The EFI block driver binds to controllers implementing the block io
protocol.
When the bind function of the EFI block driver is called it creates a
new U-Boot block device. It installs child handles for all partitions and
installs the simple file protocol on these.
The read and write functions of the EFI block driver delegate calls to the
controller that it is bound to.
A usage example is as following:
U-Boot loads the iPXE snp.efi executable. iPXE connects an iSCSI drive and
exposes a handle with the block IO protocol. It calls ConnectController.
Now the EFI block driver installs the partitions with the simple file
protocol.
iPXE uses the simple file protocol to load Grub or the Linux Kernel.
