Shawn Nematbakhsh 3fe117d346 samus_pd: Adjust input current limit downward to prevent OC ...

Based on measurements, Samus can pull more current than desired, even
taking into account the existing INPUT_CURRENT_LIMIT_OFFSET_MA
adjustment. Decrease the programmed current limit by an additional
factor, determined by taking the worst-case power measurements across 15
different Samus devices, to ensure that Samus never pulls more current
than desired.

BUG=chrome-os-partner:55297
BRANCH=samus
TEST=Verify with debug prints that curr_lim_ma becomes 256 when
negotiated current limit is 500mA and curr_lim_ma becomes 2556 when
negotiated limit is 3000mA.
