hwmon: (lm70) Code streamlining and cleanup
This fixes a byteswap bug in the LM70 temperature sensor driver, which was previously covered up by a converse bug in the driver for the LM70EVAL-LLP board (which is also fixed). Other fixes: doc updates, remove an annoying msleep(), and improve three-wire protocol handling.

This driver provides glue code connecting a National Semiconductor LM70 LLP
temperature sensor evaluation board to the kernel's SPI core subsystem.
+This is a SPI master controller driver. It can be used in conjunction with
+(layered under) the LM70 logical driver (a "SPI protocol driver").
In effect, this driver turns the parallel port interface on the eval board
into a SPI bus with a single device, which will be driven by the generic
LM70 driver (drivers/hwmon/lm70.c).
+The schematic for this particular board (the LM70EVAL-LLP) is
+available (on page 4) here:
The hardware interfacing on the LM70 LLP eval board is as follows:
