vsprintf.c: add EFI device path printing
For debugging efi_loader we need the capability to print EFI
device paths. With this patch we can write:
debug("device path: %pD", dp);
A possible output would be
device path: /MemoryMapped(0x0,0x3ff93a82,0x3ff93a82)
This enhancement is not available when building without EFI support
and neither in the SPL nor in the API example.
A test is provided. It can be executed in the sandbox with command
ut_print.
The development for EFI support in the sandbox is currently in
branch u-boot-dm/efi-working. The branch currently lacks
commit 6ea8b580f06b ("efi_loader: correct DeviceNodeToText
for media types"). Ater rebasing the aforementioned branch on
U-Boot v2018.01 the test is executed successfully.
Without EFI support in the sandbox the test is simply skipped.
