Regression fix for early omap3 revisions for wake-up events that
too some time to narrow down. Although a bit intrusive, this would
be good to get into the -rc cycle as there are quite a few boards
out there with omap3 es2.1 and es3.0, and we have those in at least
three boot test systems too that show errors without this patch.

Commit 63288b721a ("ARM: imx: fix shared gate clock") attempted to fix
an issue with particular enable/disable sequence from two shared gate
clocks. But unfortunately, while it partially fixed the issue, it also
did something wrong in .is_enabled() function hook. In case of shared
gate, the function shouldn't really query the hardware state via
share_count, because the function is trying to query the enabling state
of the clock in question, not the hardware state which is shared by
multiple clocks.
Fix the issue by returning the enable_count of the clock itself which is
maintained by clock core, in case it's a clock sharing hardware gate
with others. As the result, the initialization of share_count per
hardware state is not needed now. So remove it.

We are getting "PRM: I/O chain clock line assertion timed out" errors
on early omaps for device tree based booting. This is because we are
unconditionally calling reconfigure_io_chain while legacy booting
has omap3_has_io_chain_ctrl() checks in place in omap_hwmod.c.
For device tree based booting, we are calling reconfigure_io_chain
unconditionally from pinctrl framework. So we need to add a check for
omap3_has_io_chain_ctrl() to avoid the errors for trying to access
a register that does not exist.
For es3.0, the documentation in "4.11.2 Device Off-Mode Configuration"
just mentions PM_WKEN_WKUP[8] bit. For es3.1, there's a new chapter in
documentation for "4.11.2.2 I/O Wake-Up Mechanism" that describes the
PM_WKEN_WKUP[16] ST_IO_CHAIN bit. So PM_WKEN_WKUP[16] bit did not get
added until in es3.1 probaly to fix issues with flakey wake-up events.
We are doing proper checks for ST_IO_CHAIN already in id.c and with
omap3_has_io_chain_ctrl(). For more information, see also commit
b02b917211 ("ARM: OMAP3: PM: fix I/O wakeup and I/O chain clock
control detection").
Let's fix the issue by selecting the right function during init for
reconfigure_io_chain depending on the omap revision. For es3.0 and
earlier we need to just toggle EN_IO. By doing this, we can move the
check for omap3_has_io_chain_ctrl() from omap_hwmod.c to the init code
in prm_3xxx.c. And then we can unconditionally call reconfigure_io_chain.
Thanks to Paul Walmsley and Nishanth Menon for help with debugging the
issue.

The update_walltime() code works on the shadow timekeeper to make the
seqcount protected region as short as possible. But that update to the
shadow timekeeper does not update all timekeeper fields because it's
sufficient to do that once before it becomes life. One of these fields
is tkr.base_mono. That stays stale in the shadow timekeeper unless an
operation happens which copies the real timekeeper to the shadow.
The update function is called after the update calls to vsyscall and
pvclock. While not correct, it did not cause any problems because none
of the invoked update functions used base_mono.
commit cbcf2dd3b3 (x86: kvm: Make kvm_get_time_and_clockread()
nanoseconds based) changed that in the kvm pvclock update function, so
the stale mono_base value got used and caused kvm-clock to malfunction.
Put the update where it belongs and fix the issue.
