ARC: [nsimosci] Change .dts to use generic 8250 UART

Browse Source 
The Synopsys APB DW UART has a couple of special features that are not
in the System C model. In 3.8, the 8250_dw driver didn't really use these
features, but from 3.9 onwards, the 8250_dw driver has become incompatible
with our model.
