Echoing a reasonable limit into [1] is required as there's currently no
way for this value to be propagated from the USB stack to the charging
driver.  Otherwise the block will pull maximum 100mA off USB, which is
not enough to actually charge the running platform.

[1] /sys/class/power_supply/smbb-usbin/charge_control_limit
