Samsung mach/soc changes for v4.17

1. Add few remaining SPDX license identifiers.
2. Add cpuidle support to all Midas-based boards (including new
   GT-I9300/GT-I9305/GT-N7100/GT-N7105).
ARM: EXYNOS: Extend cpuidle support to Midas boards

Exynos4412 can only use cpuidle when running under a compatible
bootloader/firmware. The Midas family of boards, including Trats2,
have such a firmware, so allow them to use cpuidle.

Leave the Trats2 check there in order to preserve the ABI.
