soc/intel/{icl,cnl,tgl}: Always add PM1_TMR block to FADT
Provide the PM1_TMR information in the FADT even if PmTimerDisabled is set because PM timer emulation is enabled via MSR 121h so the timer will still work and can be used by things like Tianocore and Windows. Porting from 662b6cb3ed (soc/intel/skylake: Always add PM1_TMR block to FADT).
