compat-wireless: upgrade and fixup

* use INC_PR
* fix RDEPENDS
* use normal PV
* move checksums from .inc to .bb
* upgrade, because old version fails to build with a lot of errors like this:
  compat-wireless-3.5-rc5-1/include/linux/compat-3.5.h:102:8: error: redefinition of 'struct tc_fq_codel_xstats'
* 3.5.4-1 also failed:

    error: implicit declaration of function 'ssb_pcihost_register' [-Werror=implicit-function-declaration]
