[PATCH] fix:iio:common:st_sensors:st_sensors_trigger:mark symbols static where possible

[Baoyou Xie]

We get 2 warnings when biuld kernel with W=1:
drivers/iio/common/st_sensors/st_sensors_trigger.c:69:13: warning: no previous prototype
for 'st_sensors_irq_handler' [-Wmissing-prototypes]
drivers/iio/common/st_sensors/st_sensors_trigger.c:85:13: warning: no previous prototype
for 'st_sensors_irq_thread' [-Wmissing-prototypes]

In fact, these functions are only used in the file in which they are
declared and don't need a declaration, but can be made static.
so this patch marks these functions with 'static'.

Applied to the togreg branch of iio.git. Initially pushed out
as testing for the autobuilders to play with it.
