Fix CFI query responses for NOR flash
This change fixes the CFI query responses to handle NOR device
widths that are different from the bank width. Support is also
added for multi-width devices in a x8 configuration. This is
typically x8/x16 devices, but the CFI specification mentions
x8/x32 devices so those should be supported as well if they
exist.
The query response data is now replicated per-device in the bank,
and is adjusted for x16 or x32 parts configured in x8 mode.
The existing code is left in place for boards that have not
been updated to specify an explicit device_width. The VExpress
board has been updated in an earlier patch in this series so
this is the only board currently affected.
