arm64: ARM: Fix the Generic Timers interrupt active level description

The Cortex-A5x TRM states in paragraph "9.2 Generic Timer functional
description" that generic timers provide an active-LOW interrupt
output. Fix the device trees to correctly describe this.

While doing this update the CPU mask to match the number of described
CPUs as well.
