* bsp_howto/clock.t: The Shared Memory Driver no longer requires the
	special IOCTL in Clock_control. This was a hack which has existed
	since before the Classic API Timer Manager was implemented. All
	implementations of and references to Clock_control were removed.

@section IO Control
The clock driver must supply a handler for the IO control device driver
entry point. This functionality is used by other components -- notably
the Shared Memory Driver to install a wrapper for the clock interrupt
service routine. The following shows the functionality required:
@example
@group
rtems_device_driver Clock_control(
rtems_device_major_number major,
rtems_device_minor_number minor,
void *pargp
)
@{
error check the argument pointer parameter
if the command is "ISR"
invoke the clock interrupt service routine
else if the command is "NEW"
install the requested handler
@}
@end group
@end example
Prior to RTEMS 4.9, the Shared Memory MPCI Driver required a special
IOCTL in the Clock Driver. This is no longer required and the Clock
Driver does not have to provide an IOCTL method at all.
