Add internal API to enter and exit deep power-down mode. Add Kconfig
option to return to DPD whenever device is not active.
When device power management becomes more mature it should be possible
to implement it, which would allow use of DPD without having to enter
and exit DPD between consecutive transactions.

The JEDEC API defines the hardware page, sector, and block sizes.
Deprecate the Kconfig settings, remove the `erase-size-block` property,
and add `has-be32k` to indicate that 32K-byte erase is supported.
Rework the driver to use the constants instead of configured values.

move misc/util.h to sys/util.h and
create a shim for backward-compatibility.
No functional changes to the headers.
A warning in the shim can be controlled with CONFIG_COMPAT_INCLUDES.

Configuration of Erase command is specified in DTS. Hence
the corresponding changes in Kconfig are removed.

This driver is inspired from the w25qxxdv SPI NOR flash driver which was
already implementing the CFI (Common Flash Interface) for its purpose.
To handle other NOR flash a flash id table (as Linux do) which contains
the geometry for a few SPI NOR flash based on their JEDEC ID has been
introduced.
We currently support the following flash:
- W25Q80
- W25Q16
- W25Q32
- S25FL216K
- MX25UM512
The read and write functions are able to handle more then one page at a
time and return the number of bytes read or write.
Also because every NOR flash expect to disable the write protection
before writing or erasing, the write enable command is now part of the
write and erase functions.
