ARM: Removed unnecessary and unused SkyEye MMU code.

Added license header back in. I originally removed this because I mostly rewrote the file, but meh

-2.6.5 Data Abort
-There are three Abort Model in ARM arch.
-
-Early Abort Model: used in some ARMv3 and earlier implementations. In this
-model, base register wirteback occurred for LDC,LDM,STC,STM instructions, and
-the base register was unchanged for all other instructions. (oldest)
-
-Base Restored Abort Model: If a Data Abort occurs in an instruction which
-specifies base register writeback, the value in the base register is
-unchanged. (strongarm, xscale)
-
-Base Updated Abort Model: If a Data Abort occurs in an instruction which
-specifies base register writeback, the base register writeback still occurs.
-(arm720T)

-read PART B
-chap2 The System Control Coprocessor  CP15
-2.4 Register1:control register
-L(bit 6): in some ARMv3 and earlier implementations, the abort model of the
-processor could be configured:
-0=early Abort Model Selected(now obsolete)
-1=Late Abort Model selceted(same as Base Updated Abort Model)
-
-on later processors, this bit reads as 1 and ignores writes.
--------------------------------------------------------------
-So, if lateabtSig=1, then it means Late Abort Model(Base Updated Abort Model)
-    if lateabtSig=0, then it means Base Restored Abort Model
-because the ARMs which skyeye simulates are all belonged to  ARMv4,
-so I think MMUReg[1]'s bit 6 should always be 1
