in yaml files. Fix this.
Add counter to all boards supporting rtc as RTC IP now support
both rtc and counter API.
Change split in 3 parts in order to lower CI load and get shippable

The old GCC ARM Embedded website on launchpad
(https://launchpad.net/gcc-arm-embedded) has been superseeded by the new
GNU Arm Embedded one
(https://developer.arm.com/open-source/gnu-toolchain/gnu-rm).
This also means a change of name from "GCC" to "GNU". Reflect this in
the enviroment variables so that the proper term is used henceforth.
