qseecom: Vote for SFPB clock only during app loading.
SFPB clock needs to be enabled during the loading of qsee images
in QSEE. This clock is disabled after the qsee image is loaded in
QSEE.
-Moved bus table from qseecom.c to board-<target> specific files.
-Added probe and remove functions for making this driver platform
driver.
