Subject: [PATCH] arm:dt:msm8994 Correct regulator timming
Documentation describe slew-rate as "time in us it takes for the regulator to change votlage value in one step".
2s seems a lot and qpnp-lab-slew-rate is only 5000us.
So correct it as if a 1000 factor was added.
This reduce the kernel boot time of the karin windy by 80s
Tested on karin windy only
