drm/i915: Nuke PCH_JSP

JSP is based on ICP and we don't really need to differentiate
between the two. So let's just delcare JSP to be ICP.

The only slight change here is for Wa_14011294188 which we
used to apply for JSP but now we'll only apply to MCC. This
should be fine since the issue being dealt with was introduced
in TGP and inherited into MCC. JSP being derived from ICP
should not need this workaround.
