mb/supermicro/x11-lga1151-series: switch from dev.init to mb_ops.init

GPIO needs to be initialized before the IPMI device gets initialized,
so the GPIOs can be read/set by the code in CB:48096 and CB:48094. Thus,
use mainboard_ops.init for GPIO configuration instead of using the
indirection via a mainboard_enable function.

To make it more visible, that we use chip.init, rename `mainboard_init`
to `mainboard_chip_init`.

Tested successfully on X11SSM-F including the IPMI changes.
