dynamic-layers: add meta-arm to provide upstream TF-A

Default upstream TF-A implementation resides in the separate layer [1],
which needs to be included in the bblayers.conf file. Per default,
upstream recipe does not define any machine to be compatible, this
compatibilty needs to be defined by the layer that pulls meta-arm TF-A
package. This however cannot be listed as dependency, since not all BSP
flavors do require upstream TF-A, therefore direct layer dependency
cannot be added.

Add meta-arm to dynamic-layers and define compatible machines in the
bbappend, which are supported by upstream TF-A version.
