ARM: pxa: redefine the cpu_is_pxa3xx 

After introducing pxa930/pxa935 and new silicons, original cpuid rules
of XScale generation 3 can't fit new silicons. Now redefine the rule
of PXA3xx.

Only PXA300/PXA310/PXA320/PXA930/PXA935 are family members of PXA3xx.
PXA930/PXA935 are family members of PXA93x. PXA93x can be considered
as PXA3xx + CP.
