[PATCH v5 00/24] target/arm: Cleanups, new features, new cpus

[Richard Henderson]

Changes for v4:
  * Rebase on master, where the second third is upstream.
  * Add ARM_CP_EL3_NO_EL2_C_NZ flag, and use that in the
    two cpregs called out by rule RJFFP that become constant
    but not zero.
  * Set SCTLR_EL1.TSCXT for user-only.

Patches lacking review:
  01-target-arm-Handle-cpreg-registration-for-missing-.patch
  02-target-arm-Drop-EL3-no-EL2-fallbacks.patch
  20-target-arm-Enable-FEAT_CSV2_2-for-cpu-max.patch
