mainboard/google/meowth: Disable debug consent and enable S0ix
This patch disables debug consent in the devicetree. When debug
consent is set to DBC by default, it prevents some clocks from turning
off during S0ix. This blocks S0ix entry.
This patch also enables S0ix from the devicetree.
BUG=b:76163091
TEST=enter S0ix and check if slp_s0 is asserted
