Bugfix for EFM32PG12 and EFR32MG12

* Off by one error in the linker scripts reserved one word too little for the vector table
* Re-apply uvisor changes to emlib. To allow uvisor to run, we should make accesses to the romtable through uvisor's secure read gateway
* Copypasta in target name (EFM32PG12, not EFR32PG12)
* Copypasta in the pin definitions (thanks @akselsm)
* Forgot to update PortName for extra ports on MG/PG12
