[MTD] [NOR] More CFI fixups for Atmel chips

Convert CFI tables from Atmel cmdset_0001 chips to Intel format and set
BufWrite timeouts to 0 for Atmel cmdset_0001 and cmdset_0002 chips.
Some chips may indicate support for buffered writes even though they
only support dual-word writes.

The CFI fixup must run before fixup_use_write_buffers for this to work.
