examples: Use CMSIS-Driver in azure-netxduo-device-update

Added CMSIS pack config files to each platform because
by default every peripheral is set to SECURE in the
CS300 and CS310 CMSIS pack. It can be changed by
adding the CMSIS config files under the
<pack cmake lib name>/RTE/Device/<Device name>/
directory and setting the peripheral's security
in the device_cfg.h
