Rename the CamelCase defines used for the interrupt status register.
The NI6527_STATUS_IRQ bit will be set whenever the device is asserting
an interrupt. Modify the function a bit so this is the only requirement
for the interrupt to be IRQ_HANDLED. Currently an OVERFLOW interrupt is
not handled, though it's unlikely this would occur without an EDGE
interrupt.

The core will validate the insn->n value based on the actual instruction
(data[0]) that is being handled. Remove the sanity check and change the
instruction handling into a switch. This follows the normal format for

The hardware offers a 4-bit register containing the number of host
channels. However, the values of these register mean 1-16 host channels,
not 0-15. Since the dwc2_hw_params struct stores the actual number of
host channels supported instead of the raw register value, it should be
5 bits wide instead of 4.
Before this commit, hardware with 16 host channels would overflow the
field, making it appear as 0 channels.
This bug was introduced in commit 9badec2 (staging: dwc2: interpret all
hwcfg and related register at init time).

The current test for an attached enabled encoder fails if we have

believe they own the enabled encoder and so we attempt to both enable
and disable DPMS on the encoder, leading to hilarity and an OOPs:
