expressed in Hz to retrieve a value in MHz: instead of open-coding,
use the HZ_PER_MHZ definition, available in linux/units.h.

In preparation for adding a IRQ synchronization mechanism for PM suspend
add gpu_irq and mmu_irq variables to struct panfrost_device and change
functions panfrost_gpu_init() and panfrost_mmu_init() to use those.
