[PATCH v6 05/24] target/arm: Move cortex impdef sysregs to cpu_tcg.c


From: Richard Henderson
Subject: [PATCH v6 05/24] target/arm: Move cortex impdef sysregs to cpu_tcg.c
Date: Fri, 6 May 2022 13:02:23 -0500

Previously we were defining some of these in user-only mode,
but none of them are accessible from user-only, therefore
define them only in system mode.

This will shortly be used from cpu_tcg.c also.
