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.
The delay to wait for the SIM card to show up appears to be unneeded on
our modems, remove it so that we don't delay boot by 10 seconds if your
device doesn't have a SIM card installed.

uim-selection has "after *" in it's dependencies to make sure the
theoretical up to ~1min delay can't be observed. Unfortunaely this
causes incorrect dependencies ordering if one of other services depends
on ofono or modemmanager. Drop "after *" so modem can always be started
properly.
On some devices, primarily with two sim slots, modem doesn't choose
the sim automatically. Add an init script that would detect in which
slot the sim is present and configure the modem to use it.
