tipspkernel: add extra level to FILESPATH with major version in the name

Add PMV variable to contain major version by extracting first 2 numbers from PV
Insert new level to FILESPATH - PN-PV-PR:PN-PV:PN-PMV:PN:files:.
Allow keeping patches and configs generic for the series (i.e. 3.2) while
incrementing stable releases (i.e. 3.2.18)
Drop use of BP and BPN, as they don't change for the kernel
