In order to let the Performance Monitoring Unit interrupts flowing in the MPIC,
we need to unmask these interrupts in the Coherency Fabric Local Interrupt Mask
Register.

Since this register is a CPU-local register, unmasking this interrupt needs to
be done on the boot CPU when the driver initializes, but also on the secondary
CPU when they are brought up.
