storm: add code for detecting rec/dev/write protect switches' status
The gpio access code has been moved to a separate file to match other
platforms. Accessor functions are added to read different switches
state. They will be read by verstage, when it is enabled, and by
ramstage, for passing the values to depthcharge.
It is unfortunate that the gpio values are not being cached and can
change by the time CBMEM table is filled, but we have to live with
that for now.
