parisc stable patch for kernel v6.12

Hi Greg,

below is a backport for upstream patch
fd87b7783802 ("net: Fix the devmem sock opts and msgs for parisc").

This upstream patch does not apply cleanly against v6.12, and backporting all intermediate changes are too big, so I created this trivial standalone patch instead.

Can you please add the patc below to the stable queue for v6.12?

Thanks!
Helge

Subject: [PATCH] net: Fix the devmem sock opts and msgs for parisc

The devmem socket options and socket control message definitions introduced in the TCP devmem series[1] incorrectly continued the socket definitions for arch/parisc.

The UAPI change seems safe as there are currently no drivers that declare support for devmem TCP RX via PP_FLAG_ALLOW_UNREADABLE_NETMEM. Hence, fixing this UAPI should be safe.

Fix the devmem socket options and socket control message definitions to reflect the series followed by arch/parisc.
