x86, UV: Remove UV delay in starting slave cpus
commit 05e33fc20ea5e493a2a1e7f1d04f43cdf89f83ed 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.
