Bug description:
  [Impact]

  We have included the DCAP version of SGX into the linux-azure kernels
  in order to provide a signed version of this driver that can be used
  with secure boot in Azure instances.

  Since a new version of this driver was released, we should update the
  embedded driver:

  https://github.com/intel/SGXDataCenterAttestationPrimitives/tree/LD_1.33/driver/linux

  [Test Case]

  - Install the new kernel on an ACC azure instance.
  - Ensure the module loads properly.
  - Check if ECL (provided on the azure images) is working properly.

  [Regression Potential]

  The changes are extensive, but both Canonical and Microsoft perform
  validation tests on SGX. Besides that, the change is restricted to
  linux-azure running on specific instances.
