[netdrvr] myri10ge, ixgbe: remove broken select INTEL_IOATDMA

Browse Source 
We cannot select INTEL_IOATDMA in Kconfig as soon as MYRI10GE or IXGBE
is enabled since the former is not available on all architectures.

Just use a Kconfig bool {IXGBE,MYRI10GE}_DCA set to =y when DCA
support can actually be built.
