Include efa from efa-installer for 6.1 kernel

[arnaldo2792]

Issue number:

Closes #

Description of changes:

The EFA driver in the Amazon Linux kernel can have some delay between when the installer is released and it making it into the kernel tree. This adds a build step to update the driver from the installer to get the latest changes as soon as the installer is available.

As part of this change, the efa.cmake file was updated to do a serial execution of the tests to validate the available configurations in the kernel sources. This is a problem unique to Bottlerocket due to how out of tree kmod builds are treated.

Testing done:

Pending

We need the other fix where cd %{_builddir} moves out of this arch conditional

[arnaldo2792]

Forced push includes:

• Move the cd %{_builddir} line out of the conditional
• Rework modules_prepare patch, and use $(PREPARE) $(Q)$(MAKE) to support parallel tests executions in the EFA driver

(Forgot to remove the unnecessary patch for the EFA sources)

I was able to run MPI/RDMA/EFA testing to exercise the same test that produced the error for bottlerocket-os/bottlerocket#4681 and with this change the test passes:
