ARM: qcom: merge remaining subplatforms into sensible Kconfig entry

Three remaining Qualcomm platforms have special handling of the
TEXT_OFFSET to reserve the memory at the beginnig of the system RAM, see
the commit 9e775ad19f52 ("ARM: 7012/1: Set proper TEXT_OFFSET for newer
MSMs"). This is required for older platforms like IPQ40xx, MSM8x60,
MSM8960 and APQ8064 and is compatible with other 32-bit Qualcomm
platforms.
