Updates to reflect ownership changes

In September 2019 ownership of OP-TEE was transferred from Linaro to
TrustedFirmware.org and therefore we need to update the documentation to
reflect that.

- General changes from Linaro to TrustedFirmware.org.
- Updating contact information to use a TrustedFirmware.org hosted
  mailinglist.
