This is the splits the Qualcomm MSM platform into legacy support that we will
not try and convert to multiplatform and multiplatform support.
- k
Changes from v2:
* Dropped ARCH_MSM depends from CLKSRC_QCOM, since we select it
* Fixed some grammar/typo's in commit messages
* kept smp ops code in platsmp.c to match what other mach's do
* Kept mach-qcom/Kconfig sorted alphabetically
Changes from v1:
* Added patch to remove hotplug.c
* Added patch to rename msm_ to qcom_
* Changes the Kconfig to drop CPU_V7
* used wfi() in cpu_die function
* Added git tree to MAINTAINERS file

Right now hotplug.c only really implements msm_cpu_die as a wfi. Just
move that implementation into platsmp.c. At the same time we use the
existing wfi() instead of inline asm.

We intend to share the clocksource code for MSM platforms between legacy
and multiplatform supported qcom SoCs.

Introduce a new mach-qcom that will support SoCs that intend to be
multiplatform compatible while keeping mach-msm to legacy SoC/board
support that will not transition over to multiplatform.
As part of this, we move support for MSM8X60, MSM8960 and MSM8974 over
to mach-qcom.

The majority of the clocksource code for the Qualcomm platform is shared
between newer (multiplatform) and older platforms. However there is a bit
of code that isn't, so only build it for the appropriate config.

As mach-qcom will support a number of different Qualcomm SoC platforms
we replace the msm prefix on function names with qcom to be a bit more
generic.
