HWPM components (PMA, RTR, perfmon) have MMIO address space and a
corresponding virtual address region. It is possible that both MMIO and
virtual addresses are same for an aperture.
MMIO address of an aperture is used in device node to enable the
aperture and further to map HWPM component in the driver.
Virtual addresses are used by the applications to execute regops on HWPM
apertures. Virtual addresses are also used to fake aperture address
space in simulation.
This patch updates
- HWPM aperture structures to include MMIO address.
- aperture ioremap function to use MMIO address values.
- fake register allocation to use virtual address values.

Currently, dt_index aperture spec actually holds the element index of
the aperture within the IP instance. Hence, replace dt_index with
element_index to better indicate its purpose.
