efi_loader: workaround for grub lsefi bug
Patch has also been sent to fix grub to not ignore the error returned
and treat protocol_buffer_count as valid. But that that might take a
while to trickle into distro's, so this workaround might be useful.

efi_loader: disk: iterate only over valid block devices
The efi_loader currently stops iterating over the available
block devices stopping at the first device that fails.
This may imply that no block device is found.
With the patch efi_loader only iterates over valid devices.
It is based on patch 06d592bf52f6 (dm: core: Add uclass_first/next_device_check())
which is currently in u-boot-dm.git.
For testing I used an odroid-c2 with a dts including
&sd_emmc_a {
status = "okay";
};
This device does not exist on the board and cannot be initialized.

bootefi: allow return without EFI_BOOT_SERVICES.Exit
The Unified Extensible Firmware Interface Specification, version 2.7,
defines in chapter 2.1.2 - UEFI Application that an EFI application may
either directly return or call EFI_BOOT_SERVICES.Exit().
Unfortunately U-Boot makes the incorrect assumption that

dm: ofnode: use fdt32_t for DT property value to fix sparse warning
DTB is encoded in big endian. When we retrieve property values,
we need to use fdt32_to_cpu (aka be32_to_cpu) for endian conversion.
This is a bit error-prone, but sparse is useful to detect endian
