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

Flag status register polling is required for micron 512Mb flash
devices onwards, for performing erase/program operations.
Like polling for WIP(Write-In-Progress) bit in read status register,
spi_flash_cmd_wait_ready will poll for PEC(Program-Erase-Control)
bit in flag status register.

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.

Adds support for Numonyx's N25Q128 SPI flash. These devices
are used on (among others) Avnet Spartan-6 LX9 micro-evaluation
boards. Tested with "sf" commands and CONFIG_ENV_IS_IN_SPI_FLASH.

There are more than the M25Pxx serial flashs that can be
used with the stmicro driver, for example: the M25PXxx or
N25Qxx serie. All these chips have burned in the original
stmicro manufacture id 0x20 together with a standard
two-byte signature.
In preperation to support all these chips the stmicro driver
have to decode the full two-byte signature.

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.

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().

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.

Higher spi flash layers expect to be given back a pointer that was
malloced so that it can free the result, but the lower layers return
a pointer that is in the middle of the malloced memory. Reorder the
members of the lower spi structures so that things work out.

The stmicro_wait_ready() func tries to show the actual opcode that was sent
to the device, but instead it displays the array pointer. Fix it to pull
out the opcode from the start of the array.
