ARM: dts: msm: specify reg bus scaling vectors for SDE on Lahaina

Browse source 
Provide bus scaling vectors for the SDE AHB path. These values
are now moved to the device-tree for scalability.

Bus Scaling Subnodes:
- qcom,sde-reg-bus: Property to provide Bus scaling for register access for
mdss blocks.
- qcom,sde-data-bus: Property to provide Bus scaling for data bus access for
mdss blocks.
- qcom,sde-llcc-bus: Property to provide Bus scaling for data bus access for
mnoc to llcc.
- qcom,sde-ebi-bus: Property to provide Bus scaling for data bus access for
llcc to ebi.
Bus Scaling:
- interconnects An array of 4 cell properties with the format of
(src-noc master-id dst-noc slave-id) as described in:
Documentation/devicetree/bindings/interconnect/interconnect.txt
One entry for each interconnect path available.
Master/Slave ID bindings can be found at:
include/dt-bindings/interconnect/
- interconnect-names An array of string properties associated with "interconnects"
each with a unique name used to lookup the respective path.
The following paths are currently supported: qcom,sde-reg-bus,
qcom,sde-data-bus0, qcom,sde-data-bus1, qcom,sde-llcc-bus,
qcom,sde-ebi-bus
- qcom,sde-reg-bus,vectors-KBps:A series of 2 cell properties with a format of
(ab, ib) specified in kilobytes-per-second.
Used when applying reg-bus votes and must be
given whenever "qcom,sde-reg-bus" is used.
- qcom,sde-inline-rotator: A 2 cell property, with format of (rotator phandle,
instance id), of inline rotator device.
Bus Scaling Data:
- qcom,msm-bus,name: String property describing client name.
- qcom,msm-bus,num-cases: This is the number of Bus Scaling use cases
defined in the vectors property.
- qcom,msm-bus,num-paths: This represents the number of paths in each
Bus Scaling Usecase.
- qcom,msm-bus,vectors-KBps: * A series of 4 cell properties, with a format
of (src, dst, ab, ib) which is defined at
Documentation/devicetree/bindings/arm/msm/msm_bus.txt
* Current values of src & dst are defined at
include/linux/msm-bus-board.h
