Subject: [PATCH] ata: Don't build PATA_CS5535 on UML

This driver uses MSR functions that aren't implemented under UML.
Avoid building it to prevent tripping up allyesconfig.

e.g.
/usr/lib/gcc/x86_64-pc-linux-gnu/12/../../../../x86_64-pc-linux-gnu/bin/ld: pata_cs5535.c:(.text+0x3a3): undefined reference to `__tracepoint_read_msr'

I have a similar patch on my system that I have never sent.
I think that PATA_CS5536 needs the same treatment.

Anyway:

Applied to for-6.2-fixes with a slightly tweaked commit title.
Thanks !
