mb/google/brask/variants/moli: Reduce PSysMax to 11 A
Decrease PSysMax from 13.52 A to 11 A for Moli variant according to its power circuitry, implying Psys_Pmax = 11A * 19.5V = 214.5W BUG=b:215258941 Signed-off-by: Raihow Shi <raihow_shi@wistron.corp-partner.google.com> Change-Id: I61f4813f3527123a590d80b4a6e49d76ebb71c99 Reviewed-on: https://review.coreboot.org/c/coreboot/+/62374 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Tim Wawrzynczak <twawrzynczak@chromium.org> Reviewed-by: Angel Pons <th3fanbus@gmail.com>
