SPL from nand will print 'NAND' in boot_from_devices based on

This reverts commit c56ae7519f141523ba1248b22b5b5169b21772fe.
Once the 'Quad Enable' bit is cleared in their Enhanced Volatile
Configuration Register (EVCR), Micron memories expect ALL commands to use
the SPI 4-4-4 protocol. Commands using SPI 1-y-z protocols are no longer
accepted.
Within the reverted commit, the write_evcr() function is implemented using
the spi_flash_write_common(), which is a shortcut for the
[ spi_flash_cmd_write_enable(), spi_flash_cmd_write(),
spi_flash_cmd_wait_ready() ] sequence.
Since the internal state of the Micron memory has been changed when the
spi_flash_cmd_write() function completes, the later call of the
spi_flash_cmd_wait_ready() function fails.
Indeed the SPI controller driver is not aware of the SPI protocol switch.
Further patches will fix the support of Micron QSPI memories.

In spi_flash_scan, 'ret' is initialled to -1, but 'ret' is not always
used to store a return value, in that case, even when the function
succeed, an error (-1) will be returned.
Lets just return 0 if we hit the end of the function.

It is useful to name each method so that we can print out this name when
using the method. Currently this happens using a separate function. In
preparation for unifying this, add a name to each method.
The name is only available if we have libcommon support (i.e can use
printf()).

The indentation is misleading here and suggests that the write command
will be only executed in the else clause.
It seems like this is not intended, so fix the indentation to avoid
both compiler warnings and puzzled readers.

Dual flash code in spi are usually take the spi controller
to work with dual connected flash devices. Usually these
dual connection operation's are referred to flash controller
protocol rather with spi controller protocol, these are still
present in flash side for the usage of spi-nor controllers.
So, this patch remove the dual_flash options or flags in sf
which are triggered from spi controller side.

In spansion S25FS-S family the physical sectors are grouped as
normal and parameter sectors. Parameter sectors are 4kB in size
with 8 set located at the bottom or top address of a device.
Normal sectors are similar to other flash family with sizes of
64kB or 32 kB.
To erase whole flash using sector erase(D8h or DCh) won't effect
the parameter sectors, so in order to erase these we must use 4K
sector erase commands (20h or 21h) separately.
So better to erase the whole flash using 4K sector erase instead
of detecting these family parts again and do two different erase
operations.
For this:
- Removed spansion_s25fss_disable_4KB_erase code
- Add SECT_4K for S25FS512S chip
