target: don't swap MMU/no-MMU work areas
Resolve serious bug inserted by the "target: require working
area for physical/virtual addresses to be specified" patch.
It forced use of (invalid) virtual addresses when the MMU
was disabled, and vice versa.
Observed to break at least Cortex-M3, ARM926, ARM7TDMI whenever
work areas are used, such as during bulk writes to flash, DDR2,
SRAM, and so on.
Also, fix overlong lines and whitespace goofs.
