net: stmmac: remove duplicate dma queue channel macros
It doesn't need extra macros for queue 0 & 4. Same macro could
be used for all 8 queues. Related queue/channel functions could
be combined together.
Original macro which has two same parameters is unsafe macro and
might have potential side effects. Each MTL RxQ DMA channel mask
is 4 bits, so using (0xf << chan) instead of GENMASK(x + 3, x) to
avoid unsafe macro.
