ARM: OMAP: omap_device: Create a default omap_device_pm_latency
Most devices are using the same default omap_device_pm_latency structure during device built. In order to avoid the duplication of the same structure everywhere, add a default structure that will be used if the device does not have an explicit one. Next patches will clean the duplicated structures. Signed-off-by: Benoit Cousson <b-cousson@ti.com> Cc: Paul Walmsley <paul@pwsan.com> Signed-off-by: Kevin Hilman <khilman@ti.com>
