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 Change-Id: I05001a41b13e7784c34fa8f1f773fb94bbdcd01f Signed-off-by: Vaibhav Shankar <vaibhav.shankar@intel.com> Reviewed-on: https://review.coreboot.org/25312 Reviewed-by: Furquan Shaikh <furquan@google.com> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
