net: stmmac: Add support for TX/RX channel interrupt
Enable TX/RX channel interrupt registration for MAC that interrupts CPU
through shared peripheral interrupt (SPI).
Per channel interrupts and interrupt-names are registered through,
Eg: 4 tx and 4 rx channels:
interrupts = <GIC_SPI 100 IRQ_TYPE_LEVEL_HIGH>,
<GIC_SPI 101 IRQ_TYPE_LEVEL_HIGH>,
<GIC_SPI 102 IRQ_TYPE_LEVEL_HIGH>,
<GIC_SPI 103 IRQ_TYPE_LEVEL_HIGH>;
<GIC_SPI 104 IRQ_TYPE_LEVEL_HIGH>;
<GIC_SPI 105 IRQ_TYPE_LEVEL_HIGH>;
<GIC_SPI 106 IRQ_TYPE_LEVEL_HIGH>;
<GIC_SPI 107 IRQ_TYPE_LEVEL_HIGH>;
interrupt-names = "dma_tx0",
"dma_tx1",
"dma_tx2",
"dma_tx3",
"dma_rx0",
"dma_rx1",
"dma_rx2",
"dma_rx3";
