Jack Steiner 2498959a00 x86, UV: Remove UV delay in starting slave cpus ...

commit 05e33fc20e upstream.

Delete the 10 msec delay between the INIT and SIPI when starting
slave cpus. I can find no requirement for this delay. BIOS also
has similar code sequences without the delay.

Removing the delay reduces boot time by 40 sec. Every bit helps.
