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.
