This removes all occurrences of arm,num-mpu-regions relying on the value
reported by the register instead.
A user may still define this property if they need to have a compile time
definition for it.

The current atmel sam flash driver was develop based on the cortex-m7
version of smart arm microcontroller. The driver support write
protection and cache functions which is not supported by other cortex-m
variants. This fixes current driver implementation and devicetree
entries for all sam variants.
Notes:
* The cortex-m3 doesn't have support erase pages flash command and
because of that the driver still not not compatible. Keep it disabled
until a patch be send. The hwinfo driver is not affected by this
restriction.
* The sam4l variation requires a specific driver because uses another
flash controller (flashcalw). Added another compatible to
differentiate and keeped node disabled until a driver be available.

Introduce a new "zephyr,memory-region" compatible to be used when a new
memory region must be created in the linker script from the devicetree
nodes using the compatible.
Remove also the LINKER_DT_REGION_FROM_NODE macro and add a new
LINKER_DT_REGIONS macro to cycle through all the compatible regions.
In the same PR modify the DTS files and the linker scripts.

Add basic counter driver based on Timer Counter (TC) module for Atmel
SAM family.
Remarks:
- The driver is not thread safe.
- The driver does not implement guard periods.
- The driver does not guarantee that short relative alarm will trigger
the interrupt immediately and not after the full cycle / counter
overflow.
Tested on Atmel SMART SAM E70 Xplained board
