Anson Huang 263475d4e0 ARM: imx: enable RBC to support anatop LPM mode
RBC is to control whether some ANATOP sub modules
can enter lpm mode when SOC is into STOP mode, if
RBC is enabled and PMIC_VSTBY_REQ is set, ANATOP
will have below behaviors:

1. Digital LDOs(CORE, SOC and PU) are bypassed;
2. Analog LDOs(1P1, 2P5, 3P0) are disabled;

As the 2P5 is necessary for DRAM IO pre-drive in
STOP mode, so we need to enable weak 2P5 in STOP
mode when 2P5 LDO is disabled.

For RBC settings, there are some rules as below
due to hardware design:

1. All interrupts must be masked during operating
   RBC registers;
2. At least 2 CKIL(32K) cycles is needed after the
   RBC setting is changed.

Rob Herring 520f7bd733 irqchip: Move ARM gic.h to include/linux/irqchip/arm-gic.h
Now that we have GIC moved to drivers/irqchip and all GIC DT init for
platforms using irqchip_init, move gic.h and update the remaining
includes.
