Chuck Jordan 0a5bc3b0d9 spi: DW IP can have 16 slaves + SINGLE_LINE IRQ configured in soc.h ... A recent submission caused a build error for DW CONFIG_SPI_DW_INTERRUPT_SINGLE_LINE because the symbols CONFIG_SPI_<0,1>_IRQ went missing from Kconfig. I think these should probably NOT be configurable, because on an SOC, interrupt lines are hard. So I'm changing the names back to SPI_DW_PORT_<0,1>_IRQ, with there definitions originatig in the soc.h file. Also, on DesignWare ARC EM Starterkit, the SPI interface has 6 slave selects, but IP itself can handle up to 16. Why does this start from 1 and not 0? Argh! DBG_COUNTER_RESULT() should expand to 0 when not used. Also, don't check version from DesignWare IP because it can be different for each target. spi_dw_isr() requires a cast when converting arg to dev.
