[PATCH 13/17] xen: move FLASK entry under XSM in Kconfig

[Daniel De Graaf <dgdegra@tycho.nsa.gov>]

Since enabling XSM is required to enable FLASK, place the option for
FLASK below the one for XSM.  In addition, since it does not make sense
to enable XSM without any XSM providers, and FLASK is the only XSM
provider, hide the option to disable FLASK under EXPERT.
