2fb43820c2 driver_ng: implement new rmt driver 
The legacy driver can't handle the breaking change between esp chips

very well.

And it's not elegant to extend new feature like DMA, ETM.

The new driver can return a opaque handle for each RMT channel.

An obvious transaction concept was also introduced.

TX and RX functionalities are splited out.
