ARM: dts: update frequency to corner and quot mapping for CPR on msm8226v2 



Some devices need to adjust their CPR quotient value according to the cpu
frequency. The existing configuration uses the same fuse target quotient
for each frequency in a given corner. This configuration is not power
efficient as some corners have a large range of frequencies. Hence use a
virtual corner for each frequency for power saving purposes.
