of_match_device could return NULL, and so cause a NULL pointer
dereference later.
Even if the probability of this case is very low, fixing it made
static analyzers happy.

Solving this with of_device_get_match_data made also code simplier.

This driver includes clkdev.h even though it isn't used, so drop
it.

of_device_id is always used as const.
(See driver.of_match_table and open firmware functions)

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."

Palmas class of devices can provide 32K clock(s) to be used by other devices
on the board. Depending on the actual device the provided clocks can be:
CLK32K_KG and CLK32K_KGAUDIO
or only one:
CLK32K_KG (TPS659039 for example)

Use separate compatible flags for the two 32K clock.
A system which needs or have only one of the 32k clock from
Palmas will need to add node(s) for each clock as separate section
in the dts file.
The two compatible property is:
"ti,palmas-clk32kg" for clk32kg clock
"ti,palmas-clk32kgaudio" for clk32kgaudio clock

Apart from the register control of the clocks - which is done via
the clock API there is a posibility to enable the external sleep
control. In this way the clock can be enabled/disabled on demand by the
user of the clock.

See the documentation for more details.
