Input: synaptics-rmi4 - clean up F30 implementation
This patch does several cleanup changes to F30 code
- switch to using BIT() macro
- use DIV_ROUND_UP() where appropriate
- factor out code setting up and reporting buttons
- use single loop when reporting buttons: arithmetic is cheap compared to
conditionals and associated branch misprediction.
