Attn: Add ten second delay during SBE attention handling

A 10 second wait is introduced in the attention handler
path when a SBE attention is detected. This wait has been
shown to be adequate to allow the power fault handling
logic to commit a PEL and gracefully power down the host
before the SBE attention is handled. The SBE attention
handling will be preempted by the host power down sequence.
No SBE attention PEL will be committed.

Hardware Diagnostics for POWER Systems

In the event of a system fatal error reported by the internal system hardware (processor chips, memory chips, I/O chips, system memory, etc.), POWER Systems have the ability to diagnose the root cause of the failure and perform any service action needed to avoid repeated system failures.

Aditional details TBD.

Building

For a standard OpenBMC release build, you want something like:

meson -Dtests=disabled <build_dir>
ninja -C <build_dir>
ninja -C <build_dir> install

For a test / debug build, a typical configuration is:

meson -Dtests=enabled <build_dir>
ninja -C <build_dir> test
