clocksource: em_sti: Set initcall level to subsys
The reason for this is to ensure that STI is probed earlier than with its previous initcall level, module init. This came up as a problem with using CMT as a clock source kzm9g-reference which does not make use of early timers or devices. In that scenario initialisation of SDHI and MMCIF both stall on msleep() calls due to the absence of a initialised clock source. The purpose of this change is to keep the STI code in sync with the CMT code which has been modified in a similar manner.. Boot tested on: kzm9d.
