The tpm-uclass.c had tpm_uclass_post_probe and other references to
UCLASS_RNG removed, as that class does not exist in v2019.04.

tpm: allow TPM v1 and v2 to be compiled at the same time

While there is probably no reason to do so in a real life situation, it
will allow to compile test both stacks with the same sandbox defconfig.

As we cannot define two 'tpm' commands at the same time, the command for
TPM v1 is still called 'tpm' and the one for TPM v2 'tpm2'. While this
is the exact command name that must be written into eg. test files, any
user already using the TPM v2 stack can continue to do so by just writing
'tpm' because as long as TPM v1 support is not compiled, U-Boot prompt
will search for the closest command named after 'tpm'.

The command set can also be changed at runtime (not supported yet, but
ready to be), but as one can compile only either one stack or the other,
there is still one spot in the code where conditionals are used: to
retrieve the v1 or v2 command set.

* cmd/ directory:
> move existing code from cmd/tpm.c in cmd/tpm-common.c
> move specific code in cmd/tpm-v1.c

* include/ directory:

> move specific code in include/tpm-v1.h

Code designated as 'common' is compiled if TPM are used. Code designated
as 'specific' is compiled only if the right specification has been
selected.

All files include tpm-common.h.
Files in cmd/ include tpm-user-utils.h.
Files in lib/ include tpm-utils.h.
Depending on the specification, files may include either (not both)
tpm-v1.h or tpm-v2.h.

SPDX: Convert all of our single license tags to Linux Kernel style

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

dm: tpm: Add a uclass for Trusted Platform Modules

Add a new uclass for TPMs which uses almost the same TIS (TPM Interface
Specification) as is currently implemented. Since init() is handled by the
normal driver model probe() method, we don't need to implement that. Also
rename the transfer method to xfer() which is a less clumbsy name.

Once all drivers and users are converted to driver model we can remove the
old code.
