This is not exactly what this property signifies (although it does
indeed turn the regulator on if it's not)

regulator-boot-on:
  description: bootloader/firmware enabled regulator.
It's expected that this regulator was left on by the bootloader.
If the bootloader didn't leave it on then OS should turn it on
at boot but shouldn't prevent it from being turned off later.
This property is intended to only be used for regulators where
software cannot read the state of the regulator.

[PATCH 1/3] arm64: dts: qcom: sdm845-oneplus: Don't mark ts supply boot-on

[David Heidelberg via B4 Relay]

From: Casey Connolly 

The touchscreen 1.8v supply doesn't need to be enabled at boot, only
when the driver probes. Remove the regulator-boot-on property.
