i386: i8254_initclocks: set IPL_MPSAFE for clock/rtc IRQs Setting IPL_MPSAFE for the i8254/mc146818 IRQs appeases a KASSERT in apic_intr_establish() and allows the system to boot via the i8254 path. This makes testing changes to the i8254/mc146818 code much easier on modern hardware without mucking with the GENERIC config. We already set IPL_MPSAFE for these IRQs in the equivalent amd64 code. Now, setting IPL_MPSAFE is a lie: the i8254 and mc146818 IRQs are not MP-safe. However, the lie is harmless because we only reach i8254_initclocks() if (a) there is no APIC at all, or (b) we fail to calibrate the local APIC timer.
