arch: arm: Use smaller ISR stack size for 16k nRF51 SoCs

Browse source 
The 16k RAM nRF51 variants pose a challenge to get applications to fit
within the available memory. Make the default ISR stack size smaller
than the previous 2k default, but big enough to run fully functional
Bluetooth controller and host stacks.
