v5:
- As _Static_assert() is a declaration it cannot follow a label (until
C23).
Upshot of that is to compile in clang (possibly older GCC) we need
to add {} to case statements that start with QEMU_BUILD_BUG_ON()
- Add patch to handle another QEMU_BUILD_BUG_ON() case by dropping the
unnecessary check.
Suggested-by: Michael S. Tsirkin <mst@redhat.com>
Michael observed that the CXL code regularly went above the 80 character
recommendation and in many cases this was not necessary for readability.
This series is focused on tidying this up for the existing code so that
we can maintain the preferred formatting going forwards.

Bring this read function inline with the others that do
check for unexpected size values.
Also reduces line lengths to sub 80 chars.

Establishing that only register accesses of size 4 and 8 can occur
using these functions requires looking at their callers. Make it
easier to see that by using switch statements.
Assertions are used to enforce that the register storage is of the
matching size, allowing fixed values to be used for divisors of
the array indices.

v5: _Static_assert() is a declaration in C, so may not follow
a label. Hence wrap it in {} to ensure it doesn't.
Issue seen with clang builds (and in some cases at least older
GCC).
We can't wrap it in {} in the QEMU_BUILD_BUG_ON() define as that
is used in a few places outside of functions.

long lines in the CXL code in a recent review.
This patch is intended to rectify that where it does not
hurt readability.

To: qemu-devel, linux-cxl, Michael Tsirkin, Michael Tokarev
Cc: linuxarm, Fan Ni, Philippe Mathieu-Daudé
Michael Tsirkin observed that there were some unnecessarily
long lines in the CXL code in a recent review.
This patch is intended to rectify that where it does not
hurt readability.

Some older versions of GCC trip up on this one.
This check has no obvious purpose so just remove it.
