Subject: [PATCH] coresight: do not use the BIT() macro in the UAPI header

The BIT() macro definition is not available for the UAPI headers
(moreover, it can be defined differently in the user space); replace
its usage with the _BITUL() macro that is defined in <linux/const.h>.

Fixes: 237483aa5cf4 ("coresight: stm: adding driver for CoreSight STM component")
