1) Added initial PMU support for exynos5260
2) Added exynos5260_iodesc for mapping 5260 specific SFRs. We modified
exynos5_map_io so that in case of exynos5260 only exynos5260_iodesc can
be initialized.
3) Added new macros for WAKEUP MASK for 5260, and modified exynos_pm_drvinit
accordingly.
4) Adds CMU virtual addresses for exynos5260.
rebased on kgene tree for-next branch

1.7.12.4
From: Jean Pihet <jean.pihet(a)linaro.org>
Add perf support for the AARCH64 architecture. This includes the
support for:
- AARCH64 perf registers definition and hooks,
- compat mode registers use, i.e. profiling a 32-bit binary on
a 64-bit system,
- unwinding using the dwarf information from the .debug_frame
section of the ELF binary; only in 64-bit mode,
- unwinding using the frame pointer information; in 64-bit and
compat modes.
ToDo:
- add support for unwinding using the dwarf information in compat
mode. This requires some changes to the libunwind code.
Tested on ARMv7 and ARMv8 platforms. The compat mode has been tested
on ARMv8 using statically built 32-bit binaries.
