Current keystone.dtsi includes SoC specific definitions for K2HK
SoCs. In order to support two addition keystone devices, k2 Edison
and K2 Lamarr and corresponding EVMs, This patch restructure the
dts files for the following:-
- All clock nodes that are only available in k2hk SoC are moved
from keystone-clocks.dtsi to a new k2hk-clocks.dtsi include file
- The CPU nodes are now part of the soc specific k2hk.dtsi.
- Change the compatibility string to ti,k2hk-evm and change
the model name accordingly
- Finally include k2hk-clocks.dtsi in k2hk.dtsi and that in
k2hk-evm.dts

At late init all unused clocks are disabled. So clocks that were not
get before will be gated. In Keysone 2 SoC we have at least one
necessary clock that is not used by any driver - "msmcsram". This
clock is necessary, because it supplies the Multicore Shared Memory
Controller (MSMC). MSMC is the coherency interconnect and all the
coherent masters are connected to it including devices which are not
under Linux OS control. MSMC clock should not be touched even in low
power states.
So drop the clock node, otherwise 'clk_ignore_unused' parameter will
disable the clock leading to system stall.

Add keystone timer entry to keystone device tree.
This 64-bit timer is used as backup clock event device.

PA subsystem has a fixed factor clock at the input which is
input clock divided by 3. This patch adds this clock node to dts

This patch adds K2 Kepler/Hawking evm (k2hk-evm) specific dts file.
To enable re-use of bindings across multiple evms of this family,
rename current keystone.dts to keystone.dtsi and include it in the
evm specific dts file.
K2 SoC has separate ref clock inputs for various clocks. So add
separate ref clock nodes for ARM, DDR3A, DDR3B and PA PLL input
clocks in k2hk-evm.dts. While at it, rename refclkmain to
refclksys based on device User Guide naming convention
