ARM: qemu-arm: Dynamically determine timer frequency
After commit 46fc679ede5f69 ("arm: timer: get frequency for arch timer
armv7 in cp15 cntfrq") the ARM architected timer driver knows how to
determine the timer frequency at runtime by reading the CNTFRQ register,
so we don't need to hardcode the timer frequency anymore.
