MIPS: Kconfig: Fix and clarify kconfig help text for VSMP and SMTC.

Browse Source 
Only VSMP was known as SMVP and generally the help text was too short to
be helpful.

This is a kernel model which is known a VSMP but lately has been
marketesed into SMVP.
Virtual SMP uses the processor's VPEs to implement virtual
processors. In currently available configuration of the 34K processor
this allows for a dual processor. Both processors will share the same
primary caches; each will obtain the half of the TLB for it's own
exclusive use. For a layman this model can be described as similar to
what Intel calls Hyperthreading.

is presenting the available TC's of the core as processors to Linux.
On currently available 34K processors this means a Linux system will
see up to 5 processors. The implementation of the SMTC kernel differs
significantly from VSMP and cannot efficiently coexist in the same
kernel binary so the choice between VSMP and SMTC is a compile time
decision.
