boards/arm/samv7/same70-xplained: added PWM support

Browse Source 
This commit adds board level support of PWM driver to SAME70-XPLAINED
board. The functionality is tested with two new configurations

pwm:
  An example configuration with configured PWM.
pysim:
  This configuration contains support for pysimCoder application and
  includes ADC and PWM peripherals and Ethernet driver.

pysim:
This configuration includes support for pysimCoder appliaction (for further
information regarding NuttX and pysimCoder please refer to NuttX documentation).
Following peripherals are included:
ADC - AFEC0 - channels 0, 6 and 8
PWM - PWM0 - channels 0, 1, 2
Ethernet - TCP and UPD support
pwm:
This configuration is an example of PWM driver. The multichannel option is set on
and PWM is generated on channels 0, 1 and 2 for driver PWM0.
