ARM: OMAP: add support for oscillator setup
This contains startup and shutdown times for the oscillator. By default use ULONG_MAX. Oscillator setup is used for calculating and setting up latencies for sleep modes that disable oscillator. Based on a patch from Nishanth Menon <nm@ti.com>. Signed-off-by: Tero Kristo <t-kristo@ti.com> Signed-off-by: Kevin Hilman <khilman@ti.com>
