v3 cover Remove ARCH_MSM* configs

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

PATCH v3 1/3 ARM: qcom: Make an option for qcom 'a-family' platforms

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.

PATCH v3 2/3 ARM: qcom_defconfig: Enable HAVE_ARM_ARCH_TIMER

In reply to Stephen Boyd

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

PATCH v3 3/3 ARM: qcom: Drop ARCH_MSM* configs

In reply to Stephen Boyd

Drop these configs now that we select the clocksources we need via the defconfig.

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.
