ec/lenovo/h8: Add BDC detection support
* Add support for detecting BDC.
* Allows to turn off power to BDC if no card is installed.
* Should fix https://ticket.coreboot.org/issues/99 .
Add the following devicetree values:
* has_bdc_detection
Set to one to indicate that the following register are sane.
* bdc_gpio_num
SB GPIO num to read.
* bdc_gpio_lvl
SB GPIO level for card to be present (usually zero).
Don't enable BDC power if no card is detected.
As there are no devicetree values yet, the new code doesn't
have any effect.
