[U-Boot] [PATCH 1/6] rockchip: dts: rk3399-puma: fix the modelling of BIOS_DISABLE

The fixed regulator for overriding BIOS_DISABLE had been modelling
backwards (i.e. the GPIO polarity and the enable-active-low/high
property had both been inverted), causing the 'regulator' command
to always print/expect 'disabled'/'enabled' backwards.
This fixes the mix-up and models it correctly:
* the GPIO is low-active
* the regulator should be enabled (enable-active-high) during
boot-on initialisation
