The regulator framework has a set of helpers functions to be used when
the system is entering and leaving from suspend but these are not called
on Exynos platforms. This means that the .set_suspend_* function handlers
defined by regulator drivers are not called when the system is suspended.

This patch modifies Exynos Power Management Unit (PMU) initialization
implementation in following way:

- Added platform driver support for Exynos PMU IP.
- Added platform struct exynos_pmu_data to hold platform specific data.
- For each SoC's PMU support now we can add platform data and statically
  bind PMU configuration and SoC specific initialization function.
- Separate each SoC's PMU initialization function and make it as part of
  platform data.
- It also removes uses of soc_is_exynosXYZ().

In order to have a unique .c file for all pxa variants device-tree
definitions, all the initialization functions for MACHINE_START and
DT_MACHINE_START have been put together into generic.h.

The alternative would have been one pxaXXX-dt.c file per variant.

The move is necessary because each include/mach/pxaXXX.h includes the
variant register descriptions which intersects and conflicts one with
each other.

The change is a preparation for pxa-dt.c to support multiple pxa,
ie. pxa3xx and pxa27x.

The machine files including mach/pxaXXX.h all include generic.h, which
guarantees no regression should be introduced.
