[PATCH v3 3/9] ARM: at91: pm: move SAM9X60's PM under its own SoC config flag

From: Claudiu Beznea
Date: Fri Nov 29 2019 - 08:52:25 EST


Move SAM9X60's PM part under SoC config flag. This allows the building
of SAM9X60 platform withouth depending on CONFIG_SOC_AT91SAM9 flag,
allowing us to select only necessary config flags for SAM9X60.
