This commit adds a driver for the Xaptum ENF Access Card, a TPM2.0
hardware module for authenticating IoT devices and gateways.
The card consists of a SPI TPM 2.0 chip and a USB-SPI bridge. This
driver configures the bridge, registers the bridge as an SPI
controller, and adds the TPM 2.0 as an SPI device. The in-kernel TPM
2.0 driver is then automatically loaded to configure the TPM and
expose it to userspace.
Changes since v1:
* Remove empty spi cleanup function
* Fix __beXX/__eXX mismatches
* Correct typos in comments
* Add break to last case of switch
* Check result of kzalloc
