Subject: [PATCH] staging: comedi: hwdrv_apci1500: introduce z8536_reset()

Introduce a helper function to reset the Z8536 CIO device.

Spinlock the initial reset of the Z8536 chip that puts it in State 0.
The z8536_{read,write} operations already do the spinlock to protect
the indirect register access.
