For a zero-length transfer, the STOP task is not triggered
automatically by the shortcut with the event that signals
the transfer end because such event is not generated.
Trigger this task "manually" to prevent the driver getting
stuck after the address byte is acknowledged.

TWDT0 is loaded with a new value and the counter restarts counting with
it by written RST bit in Timer Control register (T0CSR) to 1. Then, the
RST bit in T0CSR register is cleared automatically on the 2nd rising
edge of T0IN clock. Since TWCP is set to 1:32, the maximum time that RST
bit is unset is 32 * (1 / 32768) ~= 980us.
Polling this bit within a critical section in current npcx watchdog
driver isn't a good approach since it might block the other interrupts
need to service them in time. This CL introduces a timeout mechanism and
removes the critical section to improve this disadvantage. Consider the
clock tolerance, 2 ms is a suitable timeout value for RST bit. We also
remove polling for WD_RUN bit in T0CSR. Npcx watchdog needs serval LFCLK
(32k Hz) clocks to stop watchdog. 1 ms is long enough for the timeout
mechanism.

NPCX PWM supports output buffet select to push-pull or open-drain. Add

During polling ITEN bit to make sure ITIM timer is enabled, we might
have the chance that npcx_itim_evt_enable() return fake error when
timeout expired but ITEN bit is set already if CONFIG_ZERO_LATENCY_IRQS
is enabled. (Since SVCall's interrupt priority is not the highest, the
other interrupts with IRQ_ZERO_LATENCY flag could preempt CPU resource
at this moment.)
In order to prevent return fake error code, this CL adjusts the check
conditions for ITEN bit and timeout.

Some SPI NOR devices, particularly Atmel and SST, power-up with block
protect bits set in the status register. These bits must be cleared
before any erase or program operation can succeed. However, blindly
clearing bits in SR is wrong as some of these are non-volatile and
control chip behavior, including quad-enable.
Add a devicetree flag to identify device-specific BP bits in the status
register that should be cleared on startup only for devices that need
them, and when set do the clear during initialization.

Reads would wait until the device was ready before issuing the first
command; writes and erases did not. Fix this documenting and changing
so that wait-for-ready is invoked only where needed, i.e. to confirm
that a WRITE_STATUS, ERASE, or PROGRAM operation has completed before
proceeding to allow more commands to be submitted. This matches Linux
spi_nor driver behavior.
