OMAP2/3 clockdomains: split shared structures so usecounting works
Previously some of the clockdomain wakeup/sleep dependency structures were shared between several domains. For the subsequent wakeup and sleep dependency usecounting patch to work, these can no longer be shared. This patch splits the shared structures apart. Signed-off-by: Paul Walmsley <paul@pwsan.com>
