drivers/mtd_spi_nor: drop .write()

The old .write() function is only used as a fall-back if .write_page()
is not implemented.
We can drop it.

drivers/mtd_spi_nor: fix hang
...
This patch releases the SPI bus when the memory devices is not found.
This frees the bus for other devices to use the bus. It also allows
future attempts to init the device.

drivers/mtd: fix Kconfig dependencies
...
Currently implementations of the MTD api are selecting the module,
this makes it easy for default backends to be selected. But the
correct modeling is simply selecting the MTD api and then selecting
a backend. BOARDs providing one of the backends can expose this and
then that backend can be selected by default.
There is also currently nothing preventing from using the MTD api
with no backend since a mock backend can easily be provided as is
done in all mtd tests.

drivers/mtd_spi_nor: fix poll on init

The while condition for polling the chip ID is broken, it will always
poll for the max ammount of retries.
Change the condition from `or` to `and` to fix the logic.

drivers/mtd_spi_nor: prevent data corruption on 'sector erase'
...
There is no difference between 4k erase and sector erase.
But sector erase would previously do `.block_erase` which would not
erase a sector (4k) but a whole block (64k).
Fortunately all boards declare `SPI_NOR_F_SECT_4K` and all file systems
don't try to erase anything smaller, so this was never triggered.
Add an `assert(0)` to crash instead of corrupting data.
