x86, xsave: Separate fpu and xsave initialization
As xsave also supports other than fpu features, it should be
initialized independently of the fpu. This patch moves this out of fpu
initialization.
There is also a lot of cross referencing between fpu and xsave
code. This patch reduces this by making xsave_cntxt_init() and
init_thread_xstate() static functions.
The patch moves the cpu_has_xsave check at the beginning of
xsave_init(). All other checks may removed then.
