When a dynamically allocated `struct comedi_device` gets automatically
unconfigured by a call to `comedi_auto_unconfig()` from a lower-level
driver's bus removal function (e.g. when a USB device is disconnected),
the class device in `dev->class_dev` (where `dev` points to the `struct
comedi_device`) is destroyed by a call to `device_destroy()` that
matches a previous call to `device_create()`.
However, if the `struct comedi_device` is still associated with an open
file object, the now invalid `dev->class_dev` pointer may still be
passed to `dev_printk()` (via `dev_dbg()` etc.), producing bogus output
or worse.
To fix this, call `get_device()` on the class device if
`device_create()` was successful. Add a matching call to `put_device()`
in `comedi_dev_kref_release()` when the `struct comedi_device` is freed.
The calls to `dev_dbg()` etc. after the call to `device_destroy()` will
still produce valid output, although the device will have been
unregistered in sysfs.

None of these files are actually using any __init type directives
and hence don't need to include <linux/init.h>. Most are just a
left over from __devinit and __cpuinit removal, or simply due to
code getting copied from one driver to the next.

Commit 559c71fe5d ("Staging: TIDSPBRIDGE: Use vm_iomap_memory for
mmap-ing instead of remap_pfn_range") had the effect of inadvertently
shifting the start of the physical memory area mapped by
pdata->phys_mempool_base. Correct this by subtracting that shift before
calling vm_iomap_memory() and adding it back afterwards.

The comedi_lrange tables are fixed length based on the 'length' value
before the array of comedi_krange 'range' values. For aesthetics, remove

Refactor the function to remove some indent levels.
Use pcmmio_dio_write() to write the polarity and enable paged registers
instead of using the for () loop to write each register in the pages.
The for () loop actually has a bug. It switches the page to the 'enab'
registers for the first port then switches to the 'pol' registers for
all remaining writes. It also was not using the pagelock spinlock to
protect the writes to the page registers. Using the pcmmio_dio_write()
helper ensures that the writes to the paged registers complete correctly.

To use interrupts the IRQ routing must be configured and interrupts
enabled. Currently both steps are being handled in pcmmio_start_intr().
Move the code that sets the IRQ routing into the attach of the board.
At this point interrupts are still disabled. The enable and polarity
bits just need to be set in pcmmio_start_intr() to enable them.
