rockchip: dts: rk3399-puma: update usbhub_enable regulator
To correctly model the usbhub_enable regulator for U-Boot, we need
to change the settings to:
* the GPIO polarity is GPIO_ACTIVE_LOW
* should be set to inactive (enable-active-low) when boot-on settings
are applied
* it can be changed at runtime (i.e. remove the always-on)
