tpm_tis_spi.c directly includes tpm_tis.h and tpm-v2.h which both
define the same enums (see e.g. TPM_ACCESS_VALID). Add an #ifndef to
prevent redeclaration errors.

TPM are shipped with a few read-only register from which we can retrieve
for instance:
- vendor ID
- product ID
- revision ID
Product and vendor ID share the same register and are already referenced
in the tpm_chip structure. Add the revision ID entry which is missing.

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.

in tpm_infineon.c
I2C protocol is not standardize for TPM 1.2.
TIS prococol is define by the Trusted Computing Group and potentially
available on several TPMs.
tpm_tis_infineon.h header is not generic enough.
Rename tpm_tis_infineon.h to tpm_tis.h and move infineon specific
defines/variables to tpm_tis_infineon.c
