efi: Rename UCLASS_EFI and IF_TYPE_EFI

Browse source 
These names are better used for access to devices provided by an EFI
layer. Use EFI_LOADER instead here, since these are only available in
U-Boot's EFI_LOADER layer.

A linker created list is used to keep track of the UEFI drivers. To create an
entry in the list the UEFI driver uses the U_BOOT_DRIVER macro specifying
UCLASS_EFI as the ID of its uclass, e.g::
UCLASS_EFI_LOADER as the ID of its uclass, e.g::
/* Identify as UEFI driver */
U_BOOT_DRIVER(efi_block) = {
.name = "EFI block driver",
.id = UCLASS_EFI,
.id = UCLASS_EFI_LOADER,
.ops = &driver_ops,

The UEFI block IO driver supports devices exposing the EFI_BLOCK_IO_PROTOCOL.
When connected it creates a new U-Boot block IO device with interface type
IF_TYPE_EFI, adds child controllers mapping the partitions, and installs the
EFI_SIMPLE_FILE_SYSTEM_PROTOCOL on these. This can be used together with the
IF_TYPE_EFI_LOADER, adds child controllers mapping the partitions, and installs
the EFI_SIMPLE_FILE_SYSTEM_PROTOCOL on these. This can be used together with the
software iPXE to boot from iSCSI network drives [4].
This driver is only available if U-Boot is configured with::
