Hello folks,
here're some fixes for libata to make NVME and TCG OPAL work:
* fix a little build break in nvme (forgotten include and Kconfig select)
* introduce sysctl knob for enabling tpm stuff at runtime
(sed-util expects since several years, so it seems that piece just might
have been forgotten when opal support was mainlined)
