182b5f3a12 alif/mpmetalport: Use MHU to notify remote cores. 
Unlike HWSEM, the MHU IRQ can wake up cores from low-power modes, making it
better suited for notifying remote cores.  Note that no special function is
required to wake up a remote core—the act of sending a message alone will
notify it.

92f056d58f alif/ospi_flash: Add 16-bit words swap flash setting. 
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.

df06bf91a5 alif/ospi_ext: Optimize XIP speed. 
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.

8807f8d01b alif/ospi_flash: Configure dummy cycles. 
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.
