Subject: [PATCH] ARM: move Risc PC-specific <asm/hardware/iomd.h> header into mach-rpc

From: Ethan Nelson-Moore <[email-masked]>
Date: Sat, 9 May 2026 20:10:36 -0700

The <asm/hardware/iomd.h> header is specific to the IOMD chip used on
the Risc PC. Move it into mach-rpc to avoid polluting asm/hardware/
with machine-specific headers.

Also take the opportunity to remove a comment with the file path from
the header, which is bad style.
