Remove hw_set_bits from pio->irq (#978) 
It is not known if this is required. This is done for consistency purposes. Related to #974

Fix dma_irqn_acknowledge_channel (#977) 
Also dma_channel_acknowledge_irq0 and dma_channel_acknowledge_irq1.
Using hw_set_bits acked every channel because INTS0/1 are WC registers.

Fixes #974.

Fix assert in adc_set_round_robin() (#698) 
The mask passed in shouldn't already be shifted by ADC_CS_RROBIN_LSB
(16) otherwise the shift in the call to hw_write_masked() would shift
all of the bits off the end of the mask, hence we should be asserting
not against ADC_CS_RROBIN_BITS (0x1f0000) but against the number of ADC
channels available.
