The OMAP34xx ES2+ TRMs do not document the CLKTRCTRL_D2D bit, even
though the clockdomain logic remains on the chip, and must be
programmed appropriately for the CORE clockdomain to go inactive.
Thanks to Rajendra Najak <rnayak@ti.com> and Richard Woodruff
<r-woodruff2@ti.com> of TI for providing more detail on this issue;
and to Jouni Högander <jouni.hogander@nokia.com> for proposing this
fix.
This patch obsoletes the D2D clockdomain workaround in pm34xx.c in
Jouni's recent patch set.
