ARM: qcom: drop most of 32-bit ARCH_QCOM subtypes

ARM: qcom: drop most of 32-bit ARCH_QCOM subtypes

Historically we had several subtypes of 32-bit Qualcomm platforms.
Nowadays they became just useless symbols in Kconfig. Drop them and pull
corresponding clocksource entries towards top-level ARCH_QCOM entry.

Note, I've left ARCH_IPQ40XX, ARCH_MSM8x60 and ARCH_MSM8960 in place,
since they have special TEXT_OFFSET handling, which can be sorted out
separately.
