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

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.

The local sst enable/disable write funcs don't really add anything
over the common API, so just inline the common calls directly.

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.

Newer SST flashes have dropped the Auto Address Increment (AAI) word
programming (WP) modes in favor of the standard page programming mode
that most flashes now support. So add a flags field to the different
flashes to support both modes with new and old styles.

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

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().

Looks like when I was encoding the sector sizes, I forgot to divide by 8
(due to the stupid marketing driven process that declares all sizes in
useless megabits and not megabytes).
