drivers:misc: ti-st: fix debugging code
debug code in TI-ST driver can be enabled by #defining
DEBUG in the first line of the code and in case debugfs
is mounted, the 2 entries in /sys/kernel/debug/ti-st/ will
also provide useful information.
These 2 were broken because of the recent changes to the parsing
logic and the registration mechanism of the protocol drivers,
this patch fixes them.
