This 'legacy' OMAP2420 McBSP2 muxing code is currently broken after recent
conversion to new mux code. The omap_mcbsp_request calling this code is
usually called after booting whereas the omap_mux_init_signal is __init
marked so null pointer dereference would occur.

Fix this by removing the muxing code and let the bootloader or board file to
do it if necessary. Remove also omap2_mcbsp_ops as there is no use for it.

The omap4_cm_wait_module_ready function would only check for
the modules to be completely functional before declaring them
ready to be accessed.
There might also be instances where in the module is actually
in idle (under h/w control) but should still be declared
accessible, as the h/w control would make it functional when
needed.

Hence make omap4_cm_wait_module_ready return true in case
the module is fully functional *or* in idle state.
Fail only if the module is fully disabled or stuck intransition.

The explaination from the TRM for the idlest bits on OMAP4 is as
below for quick reference

Module idle state:
0x0 func:     Module is fully functional, including OCP
0x1 trans:    Module is performing transition: wakeup, or sleep, or sleep
              abortion
0x2 idle:     Module is in Idle mode (only OCP part). It is functional if
              using separate functional clock
0x3 disabled: Module is disabled and cannot be accessed

Currently there is a bug in the existing omap_device core code when
extracting the hwmod structures passed to omap_device_build_ss(). This bug
gets exposed only when passing multiple hwmod structures to
omap_device_build_ss() resulting in incorrect extraction from second hwmod
structure.

This fix uses the pointer to pointer to omap_hwmod structure (array of
pointers to omap_hwmod structure) passed to omap_device_build_ss() to
correctly extract the appropriate omap_hwmod structure.

If a GPIO bank has more than one GPIO with debounce enabled, the
debounce clock will not be fully disabled before going to
idle/suspend.

In the idle path, we just do a single clk_disable() of the bank's
debounce clock.  If there are multiple debounce-enabled GPIOs in the
bank, that clocks usage count will be > 1, so the clk_disable() will
not actually disable the clock.

So the fix is to clk_disable() for every debounce-enabled GPIO in the
bank (and an equivalent clk_enable() of course.)

In order to help differentiate omap_devices from normal
platform_devices, make them all a parent of a new common parent
device.

Then, in order to determine if a platform_device is also an
omap_device, checking the parent is all that is needed.

Users of this feature are the runtime PM core for OMAP, where we need
to know if a device being passed in is an omap_device or not in order
to know whether to call the omap_device API with it.

In addition, all omap_devices will now show up under /sys/devices/omap
instead of /sys/devices/platform

This reverts commit 0007122a.

The dereference method of checking for a valid omap_device when
wrapping a platform_device is rather unsafe and dangerous.

Instead, a better way of checking for a valid omap-device is
to use a common parent device for all omap_devices, then a check
can simply be made using the device parent.  The only user of this
API was the initial version of the runtime PM core for OMAP.  This
has now been switched to check device parent, so there are no more
users of this API.

When the clockdomain layer initializes, place all clockdomains into
software-supervised mode, and clear all wakeup and sleep dependencies
immediately, rather than waiting for the PM code to do this later.
This fixes a major bug where critical sleep dependencies added by the
hwmod code are cleared during late PM init.

As a side benefit, the _init_{wk,sleep}dep_usecount() functions are no
longer needed, so remove them.
