* Remove duplicated ARM toolchain directory
* Link with archived cryptocell 310 libraries instead
of adding them as source files
* Provide default MBED_BOOT_STACK_SIZE definition
in scatter file as is done for GCC_ARM linker file
Add license identifier to files which Arm owns the copyright to,
and contain either BSD-3 or Apache-2.0 licenses. This is to address
license errors raised by scancode analysis.
mbed-os/features/cryptocell/FEATURE_CRYPTOCELL310 directory moved
to mbed-os/connectivity/drivers/cryptocell/FEATURE_CRYPTOCELL310
and restructured according to the internal proposal.
