[PATCH 1/8] OMAP: hwmod: Fix the addr spaces count API.

[Santosh Shilimkar]

From: sricharan <r.sricharan at ti.com>

The address space count API returns the number of address space
entries for a hwmod including a additional null value present in the
address space structure introduced recently. The devices which
have multiple hwmods and use device_build_ss are broken with this,
as their address resources are populated with a extra null value,
subsequently the probe fails. So fix the API not to add the null value.
