power: simplify SYS_POWER_*_SUPPORTED Kconfig options

This commit removes dependency on SYS_POWER_LOW_POWER_STATES_SUPPORTED,
SYS_POWER_DEEP_SLEEP_STATES_SUPPORTED Kconfig options. Power management
SYS_POWER_LOW_POWER_STATES, SYS_POWER_DEEP_SLEEP_STATES options depend
now directly on specific power states supported by the given SoC. This
simplifies maintenance of SoC Kconfig files.
