David Garske 0c52f3be4d Add firmware TPM 2.0 (fwTPM) implementation 
Add portable firmware TPM 2.0 implementation (fwTPM) built on wolfCrypt.
Implements 105/113 TPM 2.0 v1.38 commands (93%) as a standalone server
with socket and TIS transports, NV storage, and full CI/fuzz coverage.

Aidan Garske 978b72fb12 Improve error logging when wolfTPM2_Init fails 
Resolves #457. When the SPI device could not be opened (e.g., kernel TPM
  driver owns it), wolfTPM failed silently with no error output. Users had
  no indication of what went wrong or how to fix it.

  Changes:
  - Make TPM2_Init failed message in wolfTPM2_Init_ex always print
    (previously required --enable-debug)
  - Add SPI/I2C open failure logging in hal/tpm_io_linux.c: permission
    denied prints unconditionally, other errors print with DEBUG_WOLFTPM
  - Add autodetect scan exhaustion message (DEBUG_WOLFTPM)
  - Fix examples (caps, wrap_test, bench, pkcs7) that silently returned
    on init failure to print error code and RC string
  - Update 13 other examples to include error code in init failure message

aidan garske 01a2bb2ab1 Add hardware SPI support for Raspberry Pi 4 
- Change default TPM_SPI_CS to 1 (CE1/GPIO7) to match official
    Raspberry Pi tpm-slb9670 overlay used by LetsTrust and Infineon HATs
  - Use _spi_get_bus_and_cs() with explicit speed/mode parameters
    for proper SPI device initialization
  - Add required includes for asm/io.h and dm/device-internal.h
  - Improve debug message prefixes for clarity

  Tested on Raspberry Pi 4 with Infineon SLB9672 TPM HAT.
