ARM: 6826/1: Merge v6 and v7 DEBUG_LL DCC support
The inline assembly differences for v6 vs. v7 are purely optimizations. On a v7 processor, an mrc with the pc sets the condition codes to the 28-31 bits of the register being read. It just so happens that the TX/RX full bits the DCC support code is testing for are high enough in the register to be put into the condition codes. On a v6 processor, this "feature" isn't implemented and thus we have to do the usual read, mask, test operations to check for TX/RX full. Thus, we can drop the v7 implementation and just use the v6 implementation for both.
