Extract five helpers from i2c_bflb_transfer to reduce cognitive
complexity from ~45 to ~15:
- i2c_bflb_check_msgs: validate message lengths and 10-bit addressing
- i2c_bflb_wait_idle: busy-wait for bus idle
- i2c_bflb_wait_completion: wait for transfer end with error checks
- i2c_bflb_do_read: read path with scatter into msg buffers
- i2c_bflb_do_write: write path with 0-length probe workaround
Also check return values of i2c_bflb_read/i2c_bflb_write that were
previously ignored, and fix num_msgs <= 0 to == 0 (uint8_t).

Fix uninitialized k_timepoint_t in read/write paths that caused
undefined timeout behavior. Add early NAK/error detection in the
transfer loops to fail fast instead of spinning until timeout.
Remove unnecessary __no_optimization attributes.
Tested on Sipeed M0Sense (BL702) with I2C peripherals across
PDS sleep/wake cycles.

Switch to use k_usleep() instead of k_busy_wait() in tcan4x5x_reset()
function, waiting for the reset to complete.
Initially, the tcan4x5x_reset() function was only ever called during driver
initialization, where busy waiting for 1000 microseconds was not an issue,
but since adding device power management support, this function can now
also be called during device resume.

When the TCAN4550 nWKRQ pin is configured for VIO, the pin is an open drain
output and requires an external pull-up resistor to the VIO rail.
Since the TCAN4550 EVM does not have such a pull-up, enable it on the GPIO
to which the nWKRQ pin is connected.

zeroing CNTHCTL_EL2 traps physical timer/counter access from EL1 to EL2,
but Zephyr has no hypervisor to handle those traps.
Enabling access is the standard EL2→EL1 drop behavior.

Origin: Original
Adds a separate TX traffic class for CDC-ECM and CDC-NCM in USBD Next
to prevent a deadlock during interface provisioning.
Tested with a custom nRF53-app firmware which combines CDC-ECM /
CDC-NCM (both tested) with mDNS with USB hosts MacOS, iPadOS, and

Update TF-M to prevent TF-M runtime secure firmware to lock the internal
non-secure flash when it erases or re-program a secure area (e.g., ITS
or PS). This prevents flash lock management conflicts when Zephyr
erases or re-program a non-secure flash area it owns.
In addition, it add a fix stale pFlash state which could cause a panic
when executing a swap using external memory.

The sample has a main loop that sleep 5s every iteration. The sleep is
currently at the beginning of the loop, so we have to wait 5s before
getting the first transfer.
This make debugging with this sample troublesome.

The GPIO ISR needs both a pointer to the device object and its data block
(because the callback linked list is stored in the data block). Sicne the
device object has a built-in pointer to the data block, using that as the
ISR's argument allows obtaining all we need "for free" whereas the current
approach wastes 4 bytes of RAM per GPIO port instance.
Note that once compiled, the reworked ISR is effectively identical to the
old one (only the offset of one `ldr Rt, [Rn, #off]` changes).
