ec/lenovo/h8: Constify struct device * parameter to h8_has_* functions

h8_has_bdc() and h8_has_wwan() do not need to modify the device
structure. Hence, this change makes the struct device * parameter to
these functions as const.

This is being done in preparation to make struct device * parameter to
fill_ssdt as const.
