clk: Remove .owner field for driver
There is no need to init .owner field.
Based on the patch from Peter Griffin <peter.griffin@linaro.org>
"mmc: remove .owner field for drivers using module_platform_driver"
This patch removes the superflous .owner field for drivers which
use the module_platform_driver API, as this is overriden in
platform_driver_register anyway."

clk: wm831x: Provide is_prepared() rather than is_enabled()
Since the driver was written an is_prepared() operation has been made
possible. Since the driver uses I2C I/O only prepare operations are
provided so move the is_enabled() operation over to is_prepared().

clk: use platform_{get,set}_drvdata()
Use the wrapper functions for getting and setting the driver data using
platform_device instead of using dev_{get,set}_drvdata() with &pdev->dev,
so we can directly pass a struct platform_device.

clk: wm831x: Fix wm831x_clkout_get_parent
Current code looks strange because calling wm831x_clkout_set_parent() with 0 as
parent parameter, wm831x_clkout_get_parent() will return 1.
According to the datasheet:
R16528 (4090h) Clock Control1
BIT 0: CLKOUT output source select
0 = FLL output
1 = 32.768kHz oscillator
Thus fix the entry order in wm831x_clkout_parents[] to make it has
the same meaning as the datasheet and make the return value
of wm831x_clkout_get_parent() consistent with the parent pass to
wm831x_clkout_set_parent().

clk: wm831x: Fix update wrong register for enable/disable FLL
According to the datasheet, FLL Enable is controlled by
R16530 (4092h) FLL Control1
BIT 0: FLL Enable
0 = Disable
1 = Enable
Thus the code should update WM831X_FLL_CONTROL_1 register rather than
WM831X_FLL_CONTROL_2 register.
Also fixes a trivial typo in dev_crit message.

clk: wm831x: Add initial WM831x clock driver
The WM831x and WM832x series of PMICs contain a flexible clocking
subsystem intended to provide always on and system core clocks. It
features:
- A 32.768kHz crystal oscillator which can optionally be used to pass
through an externally generated clock.
- A FLL which can be clocked from either the 32.768kHz oscillator or
the CLKIN pin.
- A CLKOUT pin which can bring out either the oscillator or the FLL
output.
- The 32.768kHz clock can also optionally be brought out on the GPIO
pins of the device.
This driver fully supports the 32.768kHz oscillator and CLKOUT. The FLL
is supported only in AUTO mode, the full flexibility of the FLL cannot
currently be used.
Due to a lack of access to systems where the core SoC has been converted
to use the generic clock API this driver has been compile tested only.
