powerpc: Reverse stack frame marker on little endian
On little endian the stack frame marker appears reversed when dumping
memory sequentially, as is typical in xmon or gdb, eg:
c000000004733e40 0000000000000000 0000000000000000 |................|
c000000004733e50 0000000000000000 0000000000000000 |................|
c000000004733e60 0000000000000000 0000000000000000 |................|
c000000004733e70 5347455200000000 0000000000000000 |SGER............|
c000000004733e80 a700000000000000 708897f7ff7f0000 |........p.......|
c000000004733e90 0073428fff7f0000 208997f7ff7f0000 |.sB..... .......|
c000000004733ea0 0100000000000000 ffffffffffffffff |................|
c000000004733eb0 0000000000000000 0000000000000000 |................|
To make it easier to recognise, reverse the value on little endian, so
it always appears as "REGS", eg:
c000000004733e70 5245475300000000 0000000000000000 |REGS............|
