[yocto] PRINC functionality workaround

[Belisko Marek]

Hi,

after upgrading to jethro release PRINC functionality was removed by
commit : a4d530bcf55f03258078c10a123e2717444e1060 on oe-core. PRINC
functionality was used in some of our recipes so I took part from
PRINC funtionality and put is to separate method (in bbclass) [0]

I'm trying to use it in bbappend like:
inherit veryspecial_helpers
PR := ${increase_pr(5)} but this seems to be then evaluated as :
u-boot/2015.07-${increase_pr(5)} which is wrong and fails.

Any ideas what is wrong with this approach? Maybe some brackets? Many thanks.
