The nor->ready() and spansion_sr_ready() introduced earlier in this
series are used for multi-die package parts.
The nor->quad_enable() sets the volatile QE bit on each die.
The nor->erase() is hooked if the device is not configured to uniform
sectors, assuming it has 32

Cypress chips support SPINOR_OP_EN4B(B7h) to enable 4-byte addressing mode.
Cypress chips support B8h to disable 4-byte addressing mode instead of
SPINOR_OP_EX4B(E9h).
This patch defines new opcode and updates set_4byte() to support
enable/disable 4-byte addressing mode
From: Takahiro Kuwano
The spansion_sr_ready() reads status register 1 by Read Any Register
commnad. This function is called from Flash specific hook with die address
and dummy cycles to support multi-die package parts from Spansion/Cypress.

For dual/quad die package devices from Spansion/Cypress, the device's
status needs to be checked by reading status registers in all dies, by
using Read Any Register command. To support this, a Flash specific hook
that can overwrite the legacy status check is needed.

Some of Spansion/Cypress chips support volatile version of configuration

Sometimes the information in a flash's SFDP tables is wrong. Sometimes
some information just can't be expressed in the SFDP table. So,
introduce the fixup hooks to allow tailoring settings for a specific
flash.
Three hooks are added: default_init, post_sfdp, and post_bfpt.

On devices with non-uniform sector sizes like Spansion S25 or S28 family
of flashes the sector under erase does not necessarily have to be
mtd->erasesize bytes long. For example, on S28 flashes the first 128 KiB
region is composed of 32 4 KiB sectors, then a 128 KiB sector,
