[PATCH 2/3] thermal: armada_thermal: Replace mdelay with msleep in armada375_init_sensor

[Jia-Ju Bai <baijiaju1990@gmail.com>]

armada375_init_sensor() is never called in atomic context.

armada375_init_sensor() is set as ".init_sensor" in
struct armada_thermal_data.
".init_sensor" is called armada_thermal_probe().
armada_thermal_probe() is set as ".probe" in struct platform_driver.
This function is not called in atomic context.

Despite never getting called from atomic context, armada375_init_sensor()
calls mdelay() to busily wait.
This is not necessary and can be replaced with msleep() to
avoid busy waiting.

This is found by a static analysis tool named DCNS written by myself.
And I also manually check it.
