[PATCH] spi: lm70llp: fix links in doc

[Kousik Sanagavarapu]

Update links in the documentation which point to the datasheet and
schematic.

The current links don't work because National Semiconductor (which is
the manufacturer of this board and lm70) has been a part of Texas
Instruments since 2011 and hence http://www.national.com/ doesn't work
anymore.

Fixes: 78961a574037 ("spi_lm70llp parport adapter driver")
Fixes: 2b7300513b98 ("hwmon: (lm70) Code streamlining and cleanup")

I didn't find the schematic link's TI website equivalent anywhere.  The
board (not lm70) also doesn't seem to be manufactured anymore.  So just
in case someone is still using it...
