rtase: Implement the .ndo_open function

Implement the .ndo_open function to set default hardware settings
and initialize the descriptor ring and interrupts. Among them,
when requesting interrupt, because the first group of interrupts
needs to process more events, the overall structure and interrupt
handler will be different from other groups of interrupts, so it
needs to be handled separately. The first set of interrupt handlers
need to handle the interrupt status of RXQ0 and TXQ0, TXQ4~7,
while other groups of interrupt handlers will handle the interrupt
status of RXQ1&TXQ1 or RXQ2&TXQ2 or RXQ3&TXQ3 according to the
interrupt vector.
