Randall Spangler 5c808ee56c Support DPTF charger current limiting ...

This enables the AP to limit charging current via ACPI.

BUG=chrome-os-partner:23971
BRANCH=rambi
TEST=manual
    drain battery down to <90%, then plug into AC
    (charger commands at EC console, iotools at root shell)

    iotools io_write8 0x66 0x81
    iotools io_write8 0x62 0x08
    iotools io_write8 0x62 3

    charger -> dptf limit 192, I_batt=192

    charger dptf 320
    charger -> dptf limit 320, I_batt=320

    iotools io_write8 0x66 0x80
    iotools io_write8 0x62 0x08
    iotools io_read8 0x62 -> 0x05

    iotools io_write8 0x66 0x81
    iotools io_write8 0x62 0x08
    iotools io_write8 0x62 0xff

    charger -> dptf disabled, I_batt=(something > 192)

    iotools io_write8 0x66 0x80
    iotools io_write8 0x62 0x08
    iotools io_read8 0x62 -> 0xff
