Update OMAP1-specific PM infrastructure. This is a sync of what is in linux-omap for OMAP1. This mostly de-couples OMAP1 PM from OMAP2/3 PM and renames things accordingly, and removes omap2/3 specific code from OMAP1 specific headers. Original OMAP1 decoupling patch for OMAP PM branch by Paul Walmsley. Cc: Paul Walmsley <paul@pwsan.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>
