This patch series allows us to remove the ARCH_MSM* configs that live
in mach-qcom/Kconfig. They're mostly proxy configs for user selectable
clocksource configurations anyway.
Changes from v2:
* Renamed config in patch 1 to QCOM_ARCH_A_FAMILY to be less confusing
Changes from v1:
* Patch 1 replaced with one that moves config to mach-qcom/Kconfig
* Applied Arnd's acks to patches 2 and 3

We want to remove the ARCH_MSM* configs in mach-qcom/Kconfig
because they are proxy configs for selecting the right
clocksource driver and adjusting the text offset and there is no
difference between ARCH_MSM8X60 and ARCH_MSM8960 anymore.
Furthermore, there aren't configs for all the SoCs supported by
the mainline kernel, leading to confusion about which SoCs are
supported.
So, add a new config that covers all the platforms that use the
qcom clocksource driver and need the 2MB text offset adjustment
and make it def_bool y so that the defconfigs keep working
properly.

Enable this config in the defconfig so that we can delete the
selection logic surrounding it that exists in mach-qcom/Kconfig.

I suppose we could have a QCOM_B_FAMILY option as well, but it looks
like we don't need that. Maybe mention in the help text that B_FAMILY
is always supported.

Even it does not hurt, ARCH_MSM8X60, ARCH_MSM8960 and ARCH_MSM8974 could
be also removed from the defconfig. Better to do it right now, so they
won't be forgotten.
