[PATCH v4 14/14] configs: add rpi_4_wolftpm_defconfig

[Aidan Garske <aidan@wolfssl.com>]

From: Aidan <aidan@wolfssl.com>

Add a new defconfig variant for Raspberry Pi 4 that enables the
wolfTPM stack and the hardware SPI driver out of the box, so users
with an Infineon SLB9670 / SLB9672 TPM HAT can build a working
U-Boot in a single 'make rpi_4_wolftpm_defconfig && make' step.

This is a separate defconfig rather than a modification to
rpi_4_defconfig because the average RPi 4 user does not have a
TPM attached and should not pay for SPI + TPM + wolfTPM code size
by default - that was the concern raised against v3's modification
of rpi_4_defconfig.

Compared to rpi_4_defconfig this enables:
 - CONFIG_SPI / CONFIG_DM_SPI / CONFIG_BCM2835_SPI / CONFIG_CMD_SPI
   The hardware SPI controller driver added earlier in this series,
   plus the spi command for diagnostics.
 - CONFIG_TPM / CONFIG_TPM_V2 / CONFIG_CMD_TPM
   The core TPM 2.0 stack and 'tpm2' command.
 - CONFIG_TPM_WOLF / CONFIG_CMD_WOLFTPM / CONFIG_WOLFTPM_SLB9672
   wolfTPM as the active TPM backend, with SLB9672 firmware-update
   support enabled.  CONFIG_WOLFTPM_LINUX_DEV is left off so
   wolfTPM uses its native SPI HAL (the Linux-dev path is the
   QEMU+swtpm path, not the bare-metal RPi path).

No debug / unit-test config (LOG, LOGLEVEL, UNIT_TEST,
CONSOLE_RECORD, HEXDUMP) is enabled - those belong in a developer's
local .config, not in a defconfig shipped in tree.
