clk: ti: dra7-atl-clock: fix a memory leak
of_clk_add_provider makes an internal copy of the parent_names property
while its called, thus it is no longer needed after this call and can
be freed.

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: ti: dra7-atl: Provide error check for incoming parameters in set_rate
Check for valid parameters in check rate. Else, we end up getting
errors.
This occurs as part of the inital clock tree update of child clock
nodes where new_rate could be 0 for non functional clocks.

CLK: TI: Driver for DRA7 ATL (Audio Tracking Logic)
Audio Tracking Logic is designed to be used by HD Radio applications to
synchronize the audio output clocks to the baseband clock. ATL can be also
used to track errors between two reference clocks (BWS, AWS) and generate a modulated
clock output which averages to some desired frequency.
In essence ATL is generating a clock to be used by an audio codec and also
to be used by the SoC as MCLK.
To be able to integrate the ATL provided clocks to the clock tree we need
two types of DT binding:
- DT clock nodes to represent the ATL clocks towards the CCF
- binding for the ATL IP itself which is going to handle the hw
configuration
The reason for this type of setup is that ATL itself is a separate device
in the SoC, it has it's own address space and clock domain. Other IPs can
use the ATL generated clock as their functional clock (McASPs for example)
and external components like audio codecs can also use the very same clock
as their MCLK.
The ATL IP in DRA7 contains 4 ATL instences.
