This is addressing an issue where Rx interrupts were not restored for
cdcacm after the buffer had been filled (in a burst).
The Rx interrupts were only restored after the watchdog timeout of 200ms
fired.
This happened because CONFIG_SERIAL_RXDMA was set, however, for the
cdcacm driver this does not actually matter as it is relying on
uart_enablerxint to be called via the ops table.
This patch makes sure that uart_enablerxint and uart_disablerxint are
always called, independent of CONFIG_SERIAL_RXDMA, relying on the ops
table to be correct for the case where it should be only a no-op.
Currently Nuttx doesn't seem to be any real support for OTG.
In the future when OTG is supported. This Knob can be removed
and drivers can enable their pin sets based on CONFIG_OTG.
(Adding CONFIG_OTG at this time would be misleading.)

NuttX provides the UDP_BINDTODEVICE socket option. This is a UDP protocol-specific implementation of the semi-standard Linux SO_BINDTODEVICE socket option: "SO_BINDTODEVICE forces packets on the socket to only egress the bound interface, regardless of what the IP routing table would normally choose. Similarly only packets which ingress the bound interface will be received on the socket, packets from other interfaces will not be delivered to the socket." https://codingrelic.geekhold.com/2009/10/code-snippet-sobindtodevice.html
If CONFIG_NET_UDP_BINDTODEVICE is selected and a UDP socket is bound to the device, then unrecognized packets UDP packets must not be dropped, but must be forwarded along to the bound socket unconditionally.
It the typical case, this should have no impact. It does effect the applications that use DHCP and do select the UDP_BINDTODEVICE socket option.
This PR replace existing improper logic in the code and also the improper attempts to fix problems from PR #3601 and PR #3598. Those changes are improper because they expose DHCP appliction dependencies in the OS, breaking modularity and independence of the OS and application.
Tested with stm32f4discovery:netnsh with CONFIG_NET_UDP_BINDTODEVICE. A proper DHCP test setup is needed, however.
