Most extmod network drivers were being defined on a per-port basis,

This consolidates extmod driver declarations and removes the existing

This commit renames the NORETURN macro, indicating to the compiler
that a function does not return, into MP_NORETURN to maintain the same
naming convention of other similar macros.
To maintain compaitiblity with existing code NORETURN is aliased to
MP_NORETURN, but it is also deprecated for MicroPython v2.

This is only a surface level refactor, some deeper refactoring would be
possible with (for example) the SDIO interface in mimxrt and stm32, or the
BTHCI interface which is is similar on supported ports. But sticking to
cases where the macros are the same across all ports.

The byte order (endianness) seems to be swapped when read in 8D-8D-8D in
XIP mode, for most flashes, with the exception of MX which seems to swap
half-words.
This commit adds a flash setting to allow parts to enable half-word swap
when data is written, to fix this issue. By default, only endianness is
fixed.
Tested with both MX and ISSI parts on AE3, flash test and simple file
write/read.

This change increases XIP read speed to ~30Mbytes/s at 50MHz DDR:
- Enable continuous mode.
- Remove hard-coded settings.
- Set XIP continuous mode timeout.
The prefetch remains disabled. Although enabling the prefetch gives the
best performance for the CPU in XIP mode, it must be disabled when the NPU
accesses the OSPI flash.

The default dummy cycles may not match the actual flash frequency supported
by a certain board. For example, the MX chip uses 20 dummy cycles by
default which supports up to 200MHz DDR, but the maximum frequency
supported by the AE3 board is 50MHz DDR. So the dummy cycles for this
board can be as low as 6. It's important to set the correct dummy cycles,
as it results in doubling the XIP read speed, in the case of the AE3 board.
