In r1115 "Write protection handling for Atmel AT25*" the old
spi_write_status_register function was duplicated to send WREN and
EWSR commands respectively controlled by a new common wrapper function
spi_write_status_register without a reason. Both functions' resulting
code is equal apart from the opcode used. The code itself does also
differ in the macros used, but their value (apart from the opcode) is
equal. This patch adds a new parameter for the opcode to the helper
function which allows removal of the other one. This relies on the fact
that EWSR and WREN have the same INSIZE and OUTSIZE though. If that is
really seen as an issue, the sizes could be made parameters too.
This patch also changes the wrapper so that it no longer sets the
feature bits of the struct flash(ctx) argument. This may result in
changed output, because it no longer implicitly disables the debug
message in following executions. Since almost all chips had their
feature bits fixed in the previous commit, this is a minor problem.
Also, spi_write_status_enable has been dead code since r658 or so.
Remove it.

All SPI chips without a WRSR feature bit set were evaluated except the
Sanyo LF25FW203A for which no datasheet is available.
The following list includes all SPI-capable chips that still have no
WRSR feature bit set:
- AT26DF041
- AT45CS1282
- AT45DB011D
- AT45DB021D
- AT45DB041D
- AT45DB081D
- AT45DB161D
- AT45DB321C
- AT45DB321D
- AT45DB642D
All of them have no write function set and can be therefore ignored
for now.
Apart from those the generic chips are also not tagged. The opaque
flash interface should not be affected. The SFDP dummy chip is
changed to explicitly set EWSR if it can't deduce it dynamically.
The vendor detecting generic chips can't write anyway.

The ITE IT87 SPI driver uses a trick to speed up reading and writing:
If a flash chip is 512 kByte or less, the flash chip can be completely
mapped in memory and both read and write accesses are faster that way.
The current IT87 SPI code did use the parallel programmer interface for
memory mapped reads and writes, but that's the wrong abstraction. It has
been fixed to use mmio_read*/mmio_write* for that purpose.
The Winbond W83627 SPI driver uses the same trick in its read path for
all supported chip sizes. Fix it the same way.
Switch internal_chip_readn to use mmio_readn as proper abstraction.
Kudos to Michael Karcher for spotting the bugs.

Similar to modules using the opaque programmer framework (e.g. ICH Hardware
Sequencing) this uses a template struct flashchip element in flashchips.c with
a special probe function that fills the obtained values into that struct.
This allows yet unknown SPI chips to be supported (read, erase, write) almost
as if it was already added to flashchips.c.

Forced read functionality was disabled when programmer registration was
merged in r1475.
We now support registering more than one controller at once for each bus
type. This can happen e.g. if one SPI controller has an attached flash
chip and one controller doesn't. In such a case we rely on the probe
mechanism to find exactly one chip, and the probe mechanism will
remember which controller/bus the flash chip is attached to. A forced
read does not have the luxury of knowing which compatible controller to
use, so this case is handled by always picking the first one. That may
or may not be the correct one, but there is no way (yet) to specify
which controller a flash chip is attached to.

Some flash chips contain OTP memory that we cannot read or write (yet). This
prohibits us from cloning them, hence warn the user if we detect it. Not all
variations of the tagged chips contain OTP memory. They are often only
enabled on request or have there own ordering numbers. There is usually no
way to distinguish them. Because this is a supposedly seldomly used feature
the warning is shown in with dbg verbosity.
