cardem: Add SIMTRACE_MSGT_BD_CEMU_CONFIG

The new SIMTRACE_MSGT_BD_CEMU_CONFIG command can be used to set/change
a bitmask of optional features that can be enabled in the simtrace
by the host software.  This is useful for enabling features in the
firmware which are not supported by older host utilities.

The firmware will return the actually set/configured features in
response.

The feature bitmask is not yet used anywhere; it will be by subequent
patches.
