While the clk lookup table is making reference to "ohci"
other subsystems (such as phy) are trying to match "ohci.0"

Since there is a single ohci instance, instead of changing
the clk name, change the dev id to -1, and add the "-da8xx"
postfix to match the driver name that will also be changed
in a subsequent patch.

Remove fake platform device used for PM init.  Move pdata values which
are common across all current platforms into pm.c.

Also, since PM is only used on da8xx, remove davinci_pm_init() from
common init code, and only use in da850/omapl138 board files that are
currently creating the fake platform_device.

This fixes pwm name matching for DA850 familiy devices. When using device
tree, the da850_auxdata_lookup[] table caused pwm devices to have the exact
same name, which caused errors when trying to register the devices.

We cannot have multiple entries for the same clock in in da850_clks[], so
we have added child clocks to the EHRPWM and ECAP LPSC clocks so that each
PWM device will have its own clock for proper name matching.

The davinci boards don't have their clocks in DT yet and getting a clock
will fail, unless registering them as clk_lookups. This registers the
aemif clock for the ti-aemif memory driver.

The current aemif lookup entry resolving to the same clock:
    'CLK(NULL,               "aemif",        &aemif_clk)'
is currently used by davinci_nand and remains for non-DT and backward
compatibility.

Currently the davinci boards only configure the AEMIF in case of non-DT
boot, via some code in mach-davinci.
This change will allow DT-based davinci platforms to do the same, via
the ti-aemif memory driver code.

The da850 family of processors has an async3 clock domain that can be
muxed to either pll0_sysclk2 or pll1_sysclk2. Now that the davinci clocks
have a set_parent callback, we can use this to control the async3 mux
instead of a stand-alone function.

This adds a new async3_clk and sets the appropriate child clocks. The
default is use to pll1_sysclk2 since it is not affected by processor
frequency scaling.

But current davinci implementation handles multiple instances

The "index" field of struct cpufreq_frequency_table was never an
index and isn't used at all by the cpufreq core.  It only is useful

Many people nowadays blindly set it in ascending order with the
assumption that the core will use it, which is a mistake.
