For JEDEC compatible SPI NOR chips, there should be a single generic
"jedec,spi-nor" compatible.
Drop the model-specific compatible from the flash node.

GPIO lines 59 and 61 are named BT_KILL_1V8_L and WIFI_KILL_1V8_L in the
hardware design. Add them to the gpio-line-names property to make the
names available to users and developers.

The names currently given to the EC controlled regulators do not match
what is used in the hardware design.
Fix the names and the labels.

The thermistor device nodes were added before the vbus regulator and
reserved memory nodes, when they should be after them, based on
alphabetical order of the device node _name_.
Move them to the correct position. No functional changes intended.
