Subject: [PATCH v4 3/8] arm64/sysreg: Convert SPE registers to automatic generation

Convert all the SPE register defines to automatic generation. No
functional changes.

New registers and fields for SPEv1.2 are added with the conversion.

Some of the PMBSR MSS field defines are kept as the automatic generation
has no way to create multiple names for the same register bits. The
meaning of the MSS field depends on other bits.

Tested-by: James Clark <james.clark@....com>
Signed-off-by: Rob Herring <robh@...nel.org>

v4:
 - Rebase on v6.2-rc1
v3:
 - Make some fields enums and add some missing fields
v2:
 - New patch
