[Buildroot] [PATCH v5 2/3] package/libtpms: add host package

[Jarkko Sakkinen <jarkko@kernel.org>]

Libtpms is a library that targets the integration of TPM functionality
into hypervisors, primarily into Qemu. Libtpms provides a very narrow
public API for this purpose so that integration is possible. Only the
minimum of necessary APIs are made publicly available.

v5:
- Config.in.host
- s/"libtpms"/"host libtpms"/
v4:
- Changed in libtpms.mk to purely HOST_*.
v3:
- Use package deps in Kconfig as this just a library.
- DEPENDENCIES and CONF_OPTS for the host build
v2:
- Use host packages in package/libtpms/Config.in.
- Select BR2_HOST_PACKAGE_LIBOPENSSL.

+	  Libtpms is a library that targets the integration of TPM
+	  functionality into hypervisors, primarily into Qemu. Libtpms
+	  provides a very narrow public API for this purpose so that
+	  integration is possible. Only the minimum of necessary APIs
+	  are made publicly available.
+
+	  It is assumed that the user of libtpms is familiar with the
+	  concepts of the Trusted Platform Module (TPM). For the
+	  interaction with libtpms it is necessary to know how to
+	  construct valid TPM commands and to be able to parse their
+	  results. It is not within the scope of libtpms's documentation
+	  to provide background on this. See the section on references
+	  below.
