With all callbacks converted, and the timer callback prototype
switched over, the TIMER_FUNC_TYPE cast is no longer needed,
so remove it. Conversion was done with the following scripts:
perl -pi -e 's|\(TIMER_FUNC_TYPE\)||g' \
$(git grep TIMER_FUNC_TYPE | cut -d: -f1 | sort -u)
perl -pi -e 's|\(TIMER_DATA_TYPE\)||g' \
$(git grep TIMER_DATA_TYPE | cut -d: -f1 | sort -u)
The now unused macros are also dropped from include/linux/timer.h.

This is mostly updates of the usual suspects: lpfc, qla2xxx, hisi_sas,
megaraid_sas, pm80xx, mpt3sas, be2iscsi, hpsa. and a host of minor
updates.
There's no major behaviour change or additions to the core in all of
this, so the potential for regressions should be small (biggest
potential being in the scsi error handler changes).
