On a processor with caches, when you write data to memory OpenOCD invalidates
the cache lines affected. If you write to an address within 64 bytes of
UINT32_MAX, then the for loop control variable wrapped around resulting in an
infinite loop. Change control variable to be an offset from the address
involved. We should never be asked to write 2^32 bytes, so wraparound should
not be a problem.

Make the APB-AB memory read routines handle endianess order
when running on big endian host. cortex_a8_read_apb_ab_memory
is also called by cortex_a8_write_apb_ab_memory and was breaking
both APB-AB read and write functions. Also fixed bug in write
function in calculating the offset of end of buffer data. The
change aslo fixes the read issues with all combinations of
aligned unaligned memory access found by 'test_mem_access' cmd.
Tested with target "test_mem_access 4000", also size 1-9,
'mdb/h/w' 'mwb/h/w' cmds and equivalent gdb 'x' 'set' cmds.

On a target where AHB AP memory access is unavailable, care should be
taken to avoid treating addresses as virtual if the MMU was disabled
at the time the target was stopped.
Without this it's impossible to peek memory with Gdb when debugging
e.g. a bootloader because cortex_a8_read_memory() unconditionally
tried (and failed because of a sanity check in cortex_a8_mmu_modify)
to enable MMU.

Commit d9ba56c295 did a bunch of
renaming of cortex_a8 to cortex_a, including the names in config
files. However that introduced a regression as the name in target_type
struct remained unchanged.
This adds the last missing bit: actual renaming of the target name as
understood by OpenOCD.
Also change the (hopefully) last instance of using it in the supplied
config files, namely from imx6.cfg.
