bootstage: Add time accumulation feature
Sometimes we want to add up the amount of time spent in a particular activity when it is happening in a number of discrete chunks. Add bootstage_start() to mark the start of an acitivity and bootstage_accum() to accumulate the time since the last start. Calling these function in pairs results in the accumulated time being collected. Signed-off-by: Simon Glass <sjg@chromium.org>
