[RFC PATCH] efi_loader: disk: Add print to show ESP device

[Padmarao Begari]

Print a message for debug purposes when an EFI System Partition
(ESP) is detected on the device to indicate how many devices are
detected. Only one ESP device is used for capsule update; if
multiple ESP devices are found, it may indicate corruption in UEFI
variables. This is for informational purposes only, as the number
of removable media connected to a given board cannot be controlled.
