As a part of ongoing coreboot/U-Boot payload work on modern ARM64 Chromebooks, we need to decouple MediaTek's clock driver from depending on SoC targets.
This patch essentially mimicks behaviour of Qualcomm clock drivers in U-Boot, allowing us to pick them independently if we're building for coreboot target. Choosing CONFIG_TARGET_$SOC will still automatically enable the clock driver for desired target, avoiding breakage.
