Elliot Berman 573c7f061d ANDROID: Guard hooks with their CONFIG_ options ...

ANDROID_VENDOR_HOOKS has implicit dependencies on the subsystems which
it hooks into whenever it directly uses an "internal" header for that
system. For instance, drivers/scsi/ufs/ufshcd.h doesn't compile unless
CONFIG_SCSI_UFSHCD is enabled:

  In file included from drivers/android/vendor_hooks.c:41:
  In file included from include/trace/hooks/ufshcd.h:21:
  include/../drivers/scsi/ufs/ufshcd.h:675:38: error: field has incomplete type 'struct devfreq_simple_ondemand_data'
          struct devfreq_simple_ondemand_data ondemand_data;
                                              ^
  include/../drivers/scsi/ufs/ufshcd.h:675:9: note: forward declaration of 'struct devfreq_simple_ondemand_data'
          struct devfreq_simple_ondemand_data ondemand_data;

To avoid these implicit dependencies, guard any "internal" header
includes with the respective CONFIG_ options when applicable. If the
CONFIG_ option is not enabled, then the forward-declared structs are
used. This is acceptable because those hooks would not have been called
anyway since the underlying subsytem wasn't enabled.
