mb/google/dedede/var/beadrix: Update PCIe and SATA pins for low power consumption
To achieve low power consumption, we disable unused PCIe and SATA
pins at beadrix/overridetree.cb according to baseboard/devicetree.cb
and mainboard schematic. Original measured beadrix board's power
consumption is about 250 mW. After we disable unused PCIe and SATA
pins, as well as, enable the other low power MUX CL (3487086: USB

https://chromium-review.googlesource.com/c/chromiumos/platform/ec/
+/3487086), the measured power consumption achieves about 110 ~ 116
mW, as well as, meets Google battery life for 14 days in the suspend
state and Intel low power consumption about 116 mW.
BRANCH=dedede
BUG=b:204882915
TEST=on beadrix, measured power consumption meets Intel power
consumption.
