modem/msm-modem: skip SIM configuration on APQ* SoCs (MR 2632)

Browse source 
Unfortunately, msm-modem-uim-selection causes boot delays on APQ*
SoCs (without most modem functionality) at the moment. The modem will
never show up so it keeps waiting and waiting.

To allow using the same rootfs on devices that have MSM* and APQ*
variants (e.g. Samsung MSM8916 tablets), add a quick check at the
beginning of the service to cancel early when running on an APQ* SoC.
This is easy to check because the SoC is actually exposed in sysfs.
