   When the timestamp is incremented via interrupt and the interrupt
   period is greater than 1 msec, successive calls to get_timer() can
   produce inaccurate timing since the interrupts are asynchronous
   to the timing loop. For example, with an interrupt period of 10 msec
   two successive calls to get_timer() could indicate an elapsed time
   of 10 msec after only several hundred usecs -- depending on when
   the next interrupt actually occurs. This behavior can cause
   reliability issues with components such as CFI and NAND.

   This can be remedied by calling reset_timer() prior to establishing
   the base timestamp with get_timer(0), provided reset_timer()
   resets the hardware timer (rather than simply resetting only the
   timestamp). This has the effect of synchronizing the interrupts
   (and the advance of the timestamp) with the timing loop.

The outx/writex macros were using writex(addr, val) rather than
   the standard writex(val, addr), resulting in incompatibilty with
   architecture independent components. This change set uses standard
   parameter order.

   The standard Altera UART & JTAG UART as well as the OpenCores
   YANU driver are now in individual files in drivers/serial
   rather than a single file uner cpu/nios2.

Many of the help messages were not really helpful; for example, many
commands that take no arguments would not print a correct synopsis
line, but "No additional help available." which is not exactly wrong,
but not helpful either.

Commit ``Make "usage" messages more helpful.'' changed this
partially. But it also became clear that lots of "Usage" and "Help"
messages (fields "usage" and "help" in struct cmd_tbl_s respective)
were actually redundant.

This patch cleans this up - for example:

Before:
	=> help dtt
	dtt - Digital Thermometer and Thermostat

	Usage:
	dtt         - Read temperature from digital thermometer and thermostat.

After:
	=> help dtt
	dtt - Read temperature from Digital Thermometer and Thermostat

	Usage:
	dtt

Remove command name from all command "usage" fields and update
common/command.c to display "name - usage" instead of
just "usage". Also remove newlines from command usage fields.
