Now the common probing is handled in spi_flash_probe.c
hence removed the unneeded flash drivers.

Rather than each device having its own way to allocate a SPI flash
structure, use the new allocation function everywhere. This will make it
easier to extend the interface without breaking devices.

The only two drivers to write the status register do it in the same
way, so unify the implementations. This also makes the block unlock
logic the same.

Analysis of the flash drivers shows that they all use 0x20 if the erase
size is 4KiB, or 0xd8 if it's larger. So with this info in hand, we can
unify all the erase functionality in one place.

I imagine much of these constants are due to copy & pasting previous
drivers rather than an actual reflection of the hardware layout. At
any rate, inline the info that we don't care about externally as it
shrinks things nicely.

In an effort to unify the spi flash drivers further, drop all the
unused and/or duplicate command defines.

Add support of MX25L4005 and MX25L8005 according to the datasheet
http://www.mct.net/download/macronix/mx25l8005.pdf
This patch has been tested with MX25L4005 and MX25L8005

Now that the common spi_flash structure tracks all the info that these
drivers need, kill off their local state indirection and use just what
the common code provides.

Once we add a new page_size field for write lengths, we can unify the
write methods for most of the spi flash drivers.

Every spi flash uses the same write enable command, so unify this in
the common code.

No need for these to be exported as they are only accessed indirectly
via function pointers.

This patch adds a new member to struct spi_flash (u16 sector_size)
and updates the spi flash drivers to start populating it.
This parameter can be used by spi flash commands that need to round
up units of operation to the flash's sector_size.
Having this number in one place also allows duplicated code to be
further collapsed into one common location (such as erase parameter
and the detected message).

All of the spi flash drivers implement the status register polling for
detecting the device ready state, so unify them all in a new helper
function -- spi_flash_wait_ready.

At the moment, the default SPI flash subsystem is quite terse. Errors and
successes both result in a generic message. So move the useful errors and
useful successes to printf output by default.
While we're here, also convert the messages to use print_size().

new chips supported:-
MX25L1605D, MX25L3205D, MX25L6405D, MX25L12855E
out of which MX25L6405D and MX25L12855E tested on Kirkwood platforms
Modified the Macronix flash support to use 2 bytes of device id instead of 1
This was required to support MX25L12855E
