[PATCH 1/7] xen/arm: Make make_cpus_node() compile at -Og

[Andrew Cooper <andrew.cooper3@xxxxxxxxxx>]

When compiling at -Og:

  domain_build.c: In function 'make_cpus_node':
  domain_build.c:926:12: error: 'clock_valid' may be used uninitialized in this 
function [-Werror=maybe-uninitialized]
    926 |         if ( clock_valid )
        |            ^

The compiler hasn't spotted that clock_valid is always initialised after the
"if ( !compatible )" check.  Initialise clock_valid to false.
