clocksource/drivers/imx: Fix -Wunused-but-set-variable warning
All warnings (new ones prefixed by >>):
drivers/clocksource/timer-imx-gpt.c: In function 'mxc_timer_interrupt':
>> drivers/clocksource/timer-imx-gpt.c:279:18: warning: variable 'tstat' set but not used [-Wunused-but-set-variable]
279 | uint32_t tstat;
| ^~~~~
vim +/tstat +279 drivers/clocksource/timer-imx-gpt.c
The change remove the tstats assignment but not the reading of the
register, assuming the register may be a ROR (Reset On Read) which
happens in the driver's interrupt registers.
