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
pointing this out). Also fix spacing on one macro. No functional changes.

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.
