x86: nmi - nmi_watchdog boot param docs cleanup

Impact: documentation update

1) nmi_watchdog boot parameter is common to 32/64 bit modes. So
   move it from Documentation/x86/x86_64/boot-options.txt to
   Documentation/kernel-parameters.txt and integrate with.

2) Also fix [panic] keyword placement -- it ought to be at first
   position otherwise it will not be recognized.

3) Document lapic and ioapic keywords.

-  nmi_watchdog=NUMBER[,panic]
-  NUMBER can be:
-  0 don't use an NMI watchdog
-  1 use the IO-APIC timer for the NMI watchdog
-  2 use the local APIC for the NMI watchdog using a performance counter. Note
-  This will use one performance counter and the local APIC's performance
-  vector.
-  When panic is specified panic when an NMI watchdog timeout occurs.
-  This is useful when you use a panic=... timeout and need the box
-  quickly up again.
