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.

drivers/mtd_spi_nor: use single transfer to read JEDEC ID
...
Just read the JEDEC ID with a single SPI transfer, there can only
be 10 banks.
This makes adaption to QSPI much simpler because now flash functions
don't call the SPI API directly anymore.

drivers/mtd_spi_nor: derive capacity from JEDEC ID
...
Most manufacturers (Spansion, Micron & ISSI) just encode the capacity
in the second ID byte.
Old Adesto (Atmel) chips use a different scheme here.

mtd: Change API to return 0 on success
...
Returning the number of bytes written/read could return a negative integer
because a uint32_t is expected for the length in read()/write() operations.
