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.
