ARM: OMAP: hwmod: Fix the addr space, irq, dma count APIs

The address spaces, irqs and dma reqs count APIs return the
number of corresponding entries in a hwmod including a additional
null value or a -1 terminator in the structure introduced recently.
More information here:

212738a4: omap_hwmod: use a terminator record with omap_hwmod_mpu_irqs
  arrays

78183f3f: omap_hwmod: use a null structure record to terminate
  omap_hwmod_addr_space arrays

bc614958: omap_hwmod: use a terminator record with omap_hwmod_dma_info
  arrays

The issue with irqs and dma info was originally reported by Benoit Cousson.

The devices which have multiple hwmods and use device_build_ss are
broken with this, as their resources are populated with a extra null
value, subsequently the probe fails. So fix the API not to include
the array terminator in the count.
