efi: Add a media/block driver for EFI block devices
Add a block driver which handles read/write for EFI block devices. This
driver actually already exists ('efi_block') but is not really suitable
for use as a real U-Boot driver:
- The operations do not provide a udevice
- The code is designed for running as part of EFI loader, so uses
EFI_PRINT() and EFI_CALL().
- The bind method probes the device, which is not permitted
- It uses 'EFI' as its parent device
The new driver is more 'normal', just requiring its platform data be set
up in advance.
