deepin: config: Enable NO_HZ_FULL

There is reportedly no (longer) significant overhead to this when it is not enabled at runtime, see https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=804857#66 By default, without passing the nohz_full parameter, this behaves just like NO_HZ_IDLE(default), enable it by passing nohz_full=all or nohz_full=cpulist, see https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/kernel/time/Kconfig?h=v6.6#n142 https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/Documentation/admin-guide/kernel-parameters.rst?h=v6.6#n80 Signed-off-by: Wentao Guan <[email protected]>
