Remove the volatile specifiers of struct slic_shmem. Furthermore store the
bus addresses for the isr pointer, link status and statistics separately
and access the upper and lower word of these addresses by means of
[lower|upper]_32_bits(). By doing this take the endianness into account.

Use the new register accessors that use offsets instead of the slic_regs
structure to read/write registers. Since not longer needed remove the
structure completley.
Introduce the function slic_flush_write() which reads from the HOSTID
register and can be used to avoid PCI write posting. Use the function at
several critical places in the code.

This driver is for a simple 4/8 channel analog output board with 2 isolated
digital inputs and 2 isolated digital outputs. Support for these subdevices
is provided by the driver.
The boards also has a watchdog timer that can be used to reset the analog
outputs. It can also be used as a general purpose 12-bit timer when the
watchdog function is not necessary. The current support code for this
subdevice is broken. It does not follow the comedi API and requires some
out-of-tree patches in order to even work.
Remove the subdevice support. If a proper register map can be located for
this board we can add support back later.
