target: msm8996: Initialize QSEECOM when SET_ROT_ONLY is enabled

QSEECOM should be initialized, as it is required for loading the
keymaster TA (e.g., when SET_ROT_ONLY feature is eanbeld).
In addition, QSEECOM HLOS driver depends on the QSEECOM
LK driver to load the commonlibs.
Currently QSEECOM is only initialized if VERIFIED_BOOT feature is enabled.

This fix initializes QSEECOM, if SET_ROT_ONLY feature is enabled,
even without VERIFIED_BOOT feature enabled.
