This patch implements the necessary topology changes for supporting system power domain on CSS platforms. The definition of PLAT_MAX_PWR_LVL and PLAT_NUM_PWR_DOMAINS macros are removed from arm_def.h and are made platform specific. In addition, the `arm_power_domain_tree_desc[]` and `arm_pm_idle_states[]` are modified to support the system power domain at level 2. With this patch, even though the power management operations involving the system power domain will not return any error, the platform layer will silently ignore any operations to the power domain. The actual power management support for the system power domain will be added later. Change-Id: I791867eded5156754fe898f9cdc6bba361e5a379
