Linux maps PAL instructions with an ITR, but uses a DTC for PAL data. Section 11.10.2.1.3, "Making PAL Procedures Calls in Physical or Virtual Mode," of the SDM (rev 2.2), says we must therefore make all PAL calls with PSR.ic = 1 so that Linux can handle any TLB faults. PAL_CALL_IC_OFF is currently unused, and as long as we use the ITR + DTC strategy, we can't use it. So remove it. I also removed the code in ia64_pal_call_static() that conditionally cleared PSR.ic.
