sf: stmicro: dont send 4 bytes when reading status register
I can't find anywhere in the datasheet that says the status register needs
3 dummy bytes sent to it before being able to read back the first real
result. Tests on a Blackfin board show that after writing the opcode, the
status register starts coming back immediately. So only write out the
read status register opcode before polling the result.

sf: set common timeouts in seconds, not milliseconds
Since timeouts are only hit when there is a problem in the system, we
don't want to prematurely timeout on a functioning setup. Thus having
low timeouts (in milliseconds) doesn't gain us anything in the production
case, but rather increases likely hood of causing problems where none
otherwise exist.

sf: always read 5 bytes for the idcode
Some SPI flash drivers like to have extended id information available
(like the spansion flash), so rather than making it re-issue the ID cmd
to get at the last 2 bytes, have the common code read 5 bytes rather than
just 3. This also matches the Linux behavior where it always reads 5 id
bytes from all flashes.

mpc83xx: Set guarded bit on BAT that covers the end of the address space
The mpc8313erdb board currently sets DBAT6 to cover all of the final 256MiB of
address space; however, not all of this space is covered by a device. In
particular, flash sits at 0xfe000000-0xfe7fffff, and nothing is mapped
at the far end of the address space.
In zlib, there is a loop that references p[-1] if p is non-NULL. Under
some circumstances, this leads to the CPU speculatively loading from
0xfffffff8 if p is NULL. This leads to a machine check.

Add wait flags to support board/chip specific delays
The NAND flash on the TQM8548_BE modules requires a short delay after
running the UPM pattern like the MPC8360ERDK board does. The TQM8548_BE
requires a further short delay after writing out a buffer. Normally the
R/B pin should be checked, but it's not connected on the TQM8548_BE.
The corresponding Linux FSL UPM driver uses similar delay points at the
same locations. To manage these extra delays in a more general way, I
introduced the "wait_flags" field allowing the board-specific driver to
specify various types of extra delay.
