Fancy Kernel r28

- mount /cache partition as data=writeback (no journaling)
- renice systemui process priority with -17 instead of -20 (-20 was too much - the phone used the maximum CPU frequency too often)
- init.rc: set sched_rt_runtime_us and cpu.rt_runtime_us directly from here instead from fancyinit1 (wasn't applying from there)
- added bcmdhd.ko module (wifi) / load module on boot (since it is now built as a module and not kernel internal anymore)
- disable swappiness on boot if zRAM has not been enabled
- apply uniform syntax (semicolons and stuff; cosmetic only)
