Add initial device tree documentation for Maxim MAX6958/6959. As per reviewer's request mention the fact of absence the reset and power enable pins, since the hardware is quite simple.

description:
|
|
The Maxim MAX6958/6959 7-segment LED display controller provides
|
|
an I2C interface to up to four 7-segment LED digits. The MAX6959,
|
|
in comparison to MAX6958, adds input support. Type of the chip can
|
|
be autodetected via specific register read, and hence the features
|
|
may be enabled in the driver at run-time, in case they are requested
|
|
via Device Tree. A given hardware is simple and does not provide
|
|
any additional pins, such as reset or power enable.
