Exynos542x: Config: Add various configs
This patch adds "iRAM, CPU state and low power" configs which are the addresses acting as flag registers. iROM code checks CONFIG_LOWPOWER_FLAG address. If it is equal to CONFIG_LOWPOWER_EN then it jumps to the address (0x02020000+CPUID*4). This is a part of iROM logic. Rest other flags are being used at various places during kernel switching and reset. They are nowhere documented because they are part programming. These configs are serving as flags for us because they are representing the addresses in iRAM which we are using for storing and extracting CPU Status and GIC status.
