msm: apq8064: remove device registration of touchscreen FET on MTP

This power FET does not exist on apq8064 MTP and registration of
its platform device conflicts with usage of pmic gpio-23 for other
purposes on the MTP target.

msm: sglte2: prevent early bootup of the external qsc modem

The gpio connection to the KPD_PWR_N pin of the external qsc modem
is not inverted as it was in previous sglte targets so configuring
the gpio LOW initially was causing the qsc modem to boot up too
early. Change the configuration to HIGH and set the platform data
flag that tells the mdm driver that this connection is not inverted.
