[PATCH v2 1/8] OMAP: hwmod: Fix the addr spaces, irq, dma count APIs.

[sricharan <r.sricharan@ti.com>]

The address spaces, irqs and dma reqs count API returns 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 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.
