The LP1 suspend procedure is the same with Tegra30 and Tegra114. Just
need to update the difference of the register address, then we can
continue to share the code.

The flow controller can help CPU to go into suspend mode (powered-down
state). When CPU goes into powered-down state, it needs some careful
settings before getting into and after leaving. The enter and exit
functions do that by configuring appropriate mode for flow controller.
For Tegra114, the setting is compatible with Tegra30.

Nothing outside mach-tegra uses this file, so there's no need for it to
be in <mach/>.
Since uncompress.h and debug-macro.S remain in include/mach, they need
to include "../../iomap.h" becaue of this change. uncompress.h will soon
be deleted in later multi-platform/single-zImage patches. debug-macro.S
will need to continue to include this header using an explicit relative
path, to avoid duplicating the physical->virtual address mapping that
iomap.h dictates.

flowctrl_write_cpu_csr uses the cpu halt offsets and vice versa. This patch
fixes this bug.

Introduce some functions to write to the flowcontroller registers. The
flowcontroller controls CPU sleepstates and wakeup.
