arm-bsp/linux: setting the FFA_VERSION compatibility checks

Browse Source 
This commit introduces a new kernel patch that aligns the FF-A
versions checks according to the FF-A specification v1.0.

Without this fix, the FF-A bus fails to initialize when the FF-A
framework is version 1.1 (comes with the latest TF-A).

The bus driver which is v1.0 rejects the framework v1.1 despite
the fact they are compatible according to the specification.

This kernel patch changes the logic of the version checking based on
the specification.
