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



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.

	  On currently available 34K processors this means a Linux system will

	  significantly from VSMP and cannot efficiently coexist in the same

	  kernel binary so the choice between VSMP and SMTC is a compile time

	  decision.
