We don't know what the bootloader programmed here, but we want to have a
consistent value. Program the automatic input current limit detection to
re-run every 3 seconds. This seems to be necessary at least for smb5.

FWIW a random downstream clone I have sets 0x01 which is claimed to
mean "every 12s" instead
hmm I saw that too, I think more documentation would be needed to
understand this properly (I'm not exactly clear on what this actually
means, when the AICL would re-run, etc).
I have reports that this works ok, so I'd just leave it unless we have
info to suggest otherwise.
