build-yocto: replace iq-9075-evk KVM build variant with Gunyah

Replace the iq-9075-evk KVM configuration in the CI build
matrix with a Gunyah-based variant.

KVM is now enabled by default on iq-9075-evk, making the
dedicated KVM build is redundent. Replacing it with a Gunyah
configuration ensures that non-KVM virtualization paths are
still validated in CI.
