dts: qcom: vayu: Disable SLPI for now

FastRPC firmware seems to be broken, frequently says

[ 1141.986082] qcom_q6v5_pas 2400000.remoteproc: fatal error received: err_qdi.c:964:EF:sensor_process:0x1
:TMR_CLNT_1:0x80:dog_virtual_user.c:240:USER-PD DOG detects stalled initialization, triage with IMAGE OWNE
R
[ 1141.986291] remoteproc remoteproc0: crash detected in 2400000.remoteproc: type fatal error
[ 1141.986390] remoteproc remoteproc0: handling crash torvalds#28 in 2400000.remoteproc

[ 1142.016342] remoteproc remoteproc0: stopped remote processor 2400000.remoteproc

So disable SLPI for now because it does nothing other than dmesg spam
