This KSDK flash shim driver supports the device in the FRDM K64F
platform (enabled with this commit).
WARNING: the driver disables the system interrupts for potentially
long periods of time. This is required to avoid Read-While-Write
issues since most platforms run in XIP mode.

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
