flexspi driver should not interact with flash whenever possible, and
should never use flash while in a critical write or erase section.
Move device data to RAM to prevent this read-while-write hazard.

Program flow will behave incorrectly (memory and instruction fetches
return invalid data) if Flexspi is accessed by the Flexspi driver while
being used as XIP memory by the Cortex M7.
Set logging to disabled by when XIP mode is used in the memc and
flexspi drivers, and warn the user if they attempt to enable it.

This enables accessing the hyperflash through the flash api.
Added a feature to memc_mcux_flexspi that waits for flexspi bus to be
quiet.

Updating to the SDK 2.10.0 for select platforms.
west.yml:
- Update to point to the NXP HAL update with SDK 2.10.0 files
- modules/tee/tfm needed to be updated to synchronize the
LPCXPRESSO55S69 platform SDK to version 2.10.0 to be in sync
with Zephyr usage of SDK 2.10.0
drivers/counter/counter_mcux_pit.c:
- underlying SDK 2.10.0 adjusted the setting by -1 so need
to adjust the reported value set by +1
drivers/ethernet/eth_mcux.c:
- SDK2.10 ethernet driver provided an assert test that highlighted
we were using the wrong clock source on various platforms.
drivers/memc/memc_mcux_flexspi.c:
- SDK2.10 added compile time conditional on whether a field was
defined for the flexspi configuration structure.

This change allows writing to the flash while running in XIP mode,
and enables mcuboot or NVS settings to be used on i.MX RT socs.

Initially the flexspi device only supported a flash driver for
external NOR flash. As the controller supports HyperBus devices,
which can be either volatile or non-volatile, the driver iss moved
to drivers/memc.
