- fix warnings during configure cause by ecosboard. default to no, if host cpu isn't arm.

- fix generic bitbang code to allow scans to end in Shift-[ID]R

- several CFI fixes (thanks to Michael Schwingen):
 - buffer overflow when converting target code in cfi_intel_write_block -
   cfi_fix_code_endian needs the number of words, not bytes, as size
   argument.

 - Spansion flash write was completely broken on big-endian targets - I
   borrowed mechanisms from the intel driver, and moved some common code
   into the cfi_command_val helper function. There is still more common code
   that might be cleaned up.

 - the buffer size check in cfi_write was broken for spansion flashes, where
   cfi_write_words is not implemented. cfi_write_words is no only called if
   the flash does have a buffer size >1.

 - "flash info" printed CFI status information for non-CFI flashes, which is
   confusing. It now only prints those when a real CFI flash is detected.
