ARM: dts: msm: Add bwprofiler nodes to anorak

Browse Source 
Add bwprofiler nodes to anorak. The nodes include
3 bwmons, bwprof_0, bwprof_1, bpwrof_2, with each
responsible for measuring total, CPU, and GPU bandwidth
respectively.

QTI BWPROF Driver
The QTI BWPROF Driver is responsible for monitoring bandwidth counters on
Qualcomm Technologies, Inc. (QTI) chipset that represent the read/write traffic
through different interconnects in the system. The driver provides this data to
userspace clients at modest time intervals for the purpose of bandwidth
profiling.
Required properties:
- compatible: Must be "qcom,bwprof" or "qcom,bwprof-mon"
- reg: Pairs of physical base addresses and region sizes of
memory mapped registers.
- reg-names: Names of the bases for the above registers. Expected
bases are: "base", "llcc-reg", "mem-freq"
- qcom,bus-width: The width of the bus in bits.
- client: The client of bandwidth monitor, which can be either
"total", "cpu", or "gpu".
Example:
bwprof: qcom,bwprof-ddr@19090000 {
compatible = "qcom,bwprof";
#address-cells = <1>;
#size-cells = <1>;
qcom,bus-width = <16>;
ranges;
reg = <0x190BA050 0x10>;
reg-names = "mem-freq";
bwprof_0: qcom,bwprof0@19092000 {
compatible = "qcom,bwprof-mon";
reg = <0x19092000 0x1000>, <0x1A663000 0x1000>;
reg-names = "base", "llcc-reg";
client = "total";
};
bwprof_1: qcom,bwprof1@19093000 {
compatible = "qcom,bwprof-mon";
reg = <0x19093000 0x1000>, <0x1A664000 0x1000>;
reg-names = "base", "llcc-reg";
client = "cpu";
};
bwprof_2: qcom,bwprof2@19094000 {
compatible = "qcom,bwprof-mon";
reg = <0x19094000 0x1000>, <0x1A665000 0x1000>;
reg-names = "base", "llcc-reg";
client = "gpu";
};
};
