ryu: Reduce max input power to 24W
To prevent overloading inductor L2, we can't really draw too much power
from the type-C power. The voltage at L2 is around 4V, and we want to
keep the current below 6A, so let's limit the input power to 24W.
BRANCH=Ryu
BUG=None
TEST=Charge the battery on Ryu while the system is up.
