FogBugz #188457: Fix DTS entries for SOCFPGA Arria V

This commit is for the socfpga-3.10-ltsi kernel. Update the
socfpga_arria.dts file to correctly enable serial, gmac, watchdog. Also
remove the hard-coded frequencies that are no longer needed as the kernel
can use the common clock framework to get those.
