stm class: Select CONFIG_SRCU
The newly added STM code uses SRCU, but does not ensure that this code is part of the kernel: drivers/built-in.o: In function `stm_source_link_show': include/linux/srcu.h:221: undefined reference to `__srcu_read_lock' include/linux/srcu.h:238: undefined reference to `__srcu_read_unlock' drivers/built-in.o: In function `stm_source_link_drop': include/linux/srcu.h:221: undefined reference to `__srcu_read_lock' include/linux/srcu.h:238: undefined reference to `__srcu_read_unlock' This adds a Kconfig 'select' statement like all the other SRCU using drivers have.

A System Trace Module (STM) is a device exporting data in System
Trace Protocol (STP) format as defined by MIPI STP standards.
