  openrisc: define arch-specific version of nop() (2026-01-20 19:24:05 +0000)

----------------------------------------------------------------
OpenRISC updates for 6.20

The main focus for this series has been to improve OpenRISC
kernel out-of-the-box support for FPGA dev boards.

 - Adds device tree configurations for De0 Nano single and
   multicore configurations.
 - Fixes bug in OpenRISC SMP preventing the kernel from running on FPGA
   boards, due to IPIs not being unmasked on secondary CPUs in some
   configurations.
 - Picked up a fix from Brian Masney defining the nop() macro to fix
   build failures on OpenRISC for drivers using the nop() macro.
