Because both major revisions are not compatible at all, let's make them
mutually exclusive in Kconfig. This way we will be sure, when using a
command or a library function that it is supported by the right
revision.
Current drivers are currently prefixed by "tpm_", we will prefix TPMv2.x
files by "tpm2_" to make the distinction without moving everything.
The Kconfig menu about TPM drivers is now divided into two sections, one
for each specification. Compliant drivers with one specification will
only show up if this specification _only_ has been selected, otherwise a
comment is displayed.
Once a driver is selected by the user, it selects automatically a
boolean value, that is needed in order to activate the TPM commands.
Selecting the TPM commands will automatically select the right
command/library files.

When CONFIG_DM_ETH is set, we assemble the device path properly with a
full device hierarchy. Our helper function dp_fill() even put the MAC
node itself in it for us.
However, for non-DM compatibility we also have code in that added the
MAC node manually. That code now runs on top of the existing MAC node:
Handle 0x3db2f6b0
/HardwareVendor(e61d73b9-a384-4acc-aeab-82e828f3628b)[0: ]
/USBClass(0,0,9,0,0)/USBClass(424,9514,9,0,2)/MacAddr(b8:27:eb:e1:81:47,1)
/MacAddr(b8:27:eb:e1:81:47,57)/EndEntire
We obviously don't need the additional node and in fact, grub chokes on
it and fails to match the DP against the ethernet device node. So this
patch moves the additional MAC node into the non-DM code path:
Handle 0x3db3fde0
/HardwareVendor(e61d73b9-a384-4acc-aeab-82e828f3628b)[0: ]
/USBClass(0,0,9,0,0)/USBClass(424,9514,9,0,2)/MacAddr(b8:27:eb:e1:81:47,1)
/EndEntire
While at it, we also mark the non-DM MAC node as ethernet.

EFI calls are usually defined as asmlinkage. That means we pass all parameters
to functions via the stack x86_32.
On x86_64 however, we need to also stick to the MS ABI calling conventions,
which the EFIAPI define conveniently handles for us. Most EFI functions were
also marked with EFIAPI, except for the entry call.
So this patch adjusts all entry calls to use EFIAPI instead of the manual
asmlinkage attribute.
While at it, we also change the prototype of the entry point to return
efi_status_t instead of ulong, as this is the correct prototype definition.

v1 -> v2:
- Use efi_status_t in all occurences
We have 2 users of the EFI headers: efi_loader and the EFI stub. Efi_loader
always expects that the bitness of the definitions it uses is identical to
the execution.
The EFI stub however allows to run x86_64 U-Boot on 32bit EFI and the other
way around, so it allows for different bitness of EFI definitions and U-Boot
environment.
This patch explicitly requests via Kconfig that efi_loader can only be enabled
if the bitness is identical. Because we can run efi_loader on x86_64 without
EFI stub enabled, it also ensures that this case propagates the correct ABI
constraints.

This patch provides
* a uclass for EFI drivers
* a EFI driver for block devices
For each EFI driver the uclass
* creates a handle
* adds the driver binding protocol
The uclass provides the bind, start, and stop entry points for the driver
binding protocol.
In bind() and stop() it checks if the controller implements the protocol
supported by the EFI driver. In the start() function it calls the bind()
function of the EFI driver. In the stop() function it destroys the child
controllers.
The EFI block driver binds to controllers implementing the block io
protocol.
When the bind function of the EFI block driver is called it creates a
new U-Boot block device. It installs child handles for all partitions and
installs the simple file protocol on these.
The read and write functions of the EFI block driver delegate calls to the
controller that it is bound to.
A usage example is as following:
U-Boot loads the iPXE snp.efi executable. iPXE connects an iSCSI drive and
exposes a handle with the block IO protocol. It calls ConnectController.
Now the EFI block driver installs the partitions with the simple file
protocol.
iPXE uses the simple file protocol to load Grub or the Linux Kernel.
