net: tsec: Remove tx snooping support from LS1

Remove the DMCTRL Tx snooping bits (TDSEN and TBDSEN) as a
workaround for LS1.  It has been observed that currently
the Tx stops functioning after a fair amount of Tx traffic
with these settings on.  These bits are sticky and once set
they cannot be reset from Linux, for instance.
