Andrey Smirnov dba153bbce at91smad: Fixes to 'samd_protect'
Some fixes to 'samd_protect' including:
     - Fix a bug in which the value of 'set' parameter passed into the
     function was ignored so it was impossible to remove flash
     protection once it was set.
     - Check the protection status of the sector via 'is_protected'
     field of the  corresponding 'flash_sector' structure to see if
     any actual HW manipulations needs to be done.
     - Change the way the errors during protection activation are
     handled. Now even in the case of error in the middle of
     protecting a number of sectors the subroutine would still update
     the state of the sector protection in sectors array so as to
     avoid cases where openocd thinks that the sector is not protected
     while it actually is.

Remove 'first' and 'last' checks in 'samd_protect' since those
parameters are checked in 'handle_flash_erase_command'.

Make the chip information lookup tables const (thanks to Spencer Oliver for

Andrey Yurovsky 215c41c017 add support for Atmel SAMD NOR Flash
This adds a new NOR Flash driver, "at91samd", which supports the
built-in Flash on Atmel's D-series Cortex M MCUs, starting with the D20.
Parts and their geometry are detected automatically using the DSU and
lookup schemes described in the D20 document, 42129F–SAM–10/2013.
Future D-series variants and families should presumably use this
controller as well (possibly with minor changes and improvements).

Tested on the SAMD20 Xplained Pro board, for which we also add the
corresponding Flash configuration.
