    	    ARM: pxa: add iwmmx support for PJ4
    
    which does:
    
    -       mrc     p15, 0, r2, c15, c1, 0
    -       orr     r2, r2, #0x3                    @ enable access to CP0 and CP1
    -       mcr     p15, 0, r2, c15, c1, 0
    +       @ enable access to CP0 and CP1
    +       XSC(mrc p15, 0, r2, c15, c1, 0)
    +       XSC(orr r2, r2, #0x3)
    +       XSC(mcr p15, 0, r2, c15, c1, 0)
    
    but then later does:
    
    -       mrc     p15, 0, r4, c15, c1, 0
    -       orr     r4, r4, #0x3                    @ enable access to CP0 and CP1
    -       mcr     p15, 0, r4, c15, c1, 0
    +       @ enable access to CP0 and CP1
    +       XSC(mrc p15, 0, r4, c15, c1, 0)
    +       XSC(orr r4, r4, #0xf)
    +       XSC(mcr p15, 0, r4, c15, c1, 0)
