ARM: shmobile: armadillo800eva reference: Remove C board code 



Now when the r8a7740 generic multiplatform case has the same
features as the DT reference board code then get rid of the
Armadillo800EVA DT reference C board code. DT Reference code
in the future shall make use of the r8a7740 Multiplatform
support code with the generic SoC machine vector.

	   Use reference implementation of Armadillo800 EVA board support
