Add the necessary infrstructure to support power management for the
QMSI Flash driver. If deep sleep is supported, this driver supports
saving its context to be restored on resume.

The W25QXXDV_PAGE_SIZE is not a valid erase size supported by
the flash component (section 7.2.23 - 7.2.26 of datasheet
https://www.winbond.com/resource-files/w25q16dv_revi_nov1714_web.pdf)
and it is not used by any code so remove it.

Calls to flash write or erase operations can get preempted
in the middle of the API call if a concurrent call (from
other fiber or task) to the same API is made. The patch ensures
concurrent API calls from other fiber/task is put on hold until
the current operation is completed.
The mechanism is by default not activated. To enable
it, the following flag needs to be defined:
CONFIG_SOC_FLASH_QMSI_API_REENTRANCY

If the driver fails initializations, do not set the driver_api.
This follows the idea that device_get_binding() will not return
a reference to the driver instance when driver init fails.

This patch replaces all occurences of the macro DEV_NO_SUPPORT by
-ENODEV at the driver level. So this patch touch the files under
drivers/, include/ and samples/drivers/ when applicable.
This patch is part of the effort to transition from DEV_* codes to
errno.h codes.

Now that the internal libc has the off_t type it's the natural choice
for the offset parameters in the flash API.

This makes the ordering consistent e.g. with SPI, Bluetooth and
Networking APIs. This also follows the order of parameters in the
POSIX read/write APIs.

size_t is the natural type for any integer that describes a number of
bytes. For the actual data use void pointers to avoid callers having
to do explicit typecasts if the data doesn't originate in a uint8_t
array. Also use a const pointer for writing to avoid typecasts for
data that originates in a const location.
