ARM: dts: msm: add wdi scaling exceptions

For WLAN LAN-LAN use cases, there won't be any other peripheral
vote and IPA vote will not scale correctly. Make changes to
add scaling exceptions to vote correctly for WLAN standalone cases.
Also increase number of buffers on LAN_CONS pipe to 224 to reduce
backpressure towards WLAN.
