* when -mcpu is given, e.g. -mcpu=em4_dmips,-mnorm,-mdiv_em
etc. are already given, no need to duplicate
* use zephyr_compiler_options to replace zephyr_cc_option
zephyr_cc_option will do compile option check first then add
the checked options into option list. It's too strict that makes
options like -mfpu, -mmpy-option cannot be added.

Update the files which contain no license information with the
'Apache-2.0' SPDX license identifier. Many source files in the tree are
missing licensing information, which makes it harder for compliance
tools to determine the correct license.
By default all files without license information are under the default
license of Zephyr, which is Apache version 2.
