mtd: spi-nor-core: Add the ->ready() hook
Commit 24b1e2c690fb953a3a981a282e37de5a0f1a98b1 upstream.
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.
