ARM: dts: msm: Update maximum bus vote for QPIC on MDM9607

With the current maximum bus voting, the PCNOC runs at 133MHz,
which pushes the system to run in turbo mode. To save power,
reduce this maximum vote of PCNOC upto 100MHz. Also, running
at turbo frequency doesn't improve performance on NAND
but will only consume more power in the use cases where
NAND is active.
