[PATCH] x86/kconfig: Remove residual "no-hlt" boot parameter reference

[PATCH] x86/kconfig: Remove residual "no-hlt" boot parameter reference

[zhenwei.pi]

The "no-hlt" boot parameter has been removed ~5 years ago :
	The commit 27be457000211a6903968dfce06d5f73f051a217
	("x86 idle: remove 32-bit-only "no-hlt" parameter, hlt_works_ok flag")

Remove a stale reference from the documentation as well.

That description is stale in other ways as well (nobody uses floppies anymore), 
I'd just remove it altogether, starting with this:

                                                                If you get
          random kernel OOPSes or reboots that don't seem to be related to
          anything, try disabling/enabling this option (or disabling/enabling
          APM in your BIOS).
	  [...]

Thanks,
