Add max device width parameter for NOR devices

For handling CFI and device ID reads, we need to not only know the
width that a NOR flash device is configured for, but also its maximum
width. The maximum width addressing mode is used for multi-width
parts no matter which width they are configured for. The most common...

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...

Fix NOR flash device ID reading

Fix NOR flash manufacturer and device ID reading. This now
properly takes into account device widths and device max widths
as required. The reading of these IDs uses the same max_width
dependent addressing as CFI queries....

Add device-width property to pflash_cfi01

The width of the devices that make up the flash interface
is required to mask certain commands, in particular the
write length for buffered writes. This length will be presented
to each device on the interface by the program writing the flash,...

return status for each NOR flash device

Now that we know how wide each flash device that makes up the bank is,
return status for each device in the bank. Leave existing code
that treats 32 bit wide banks as composed of two 16 bit devices as otherwise
we may break configurations that do not set the device_width propery....
