Add option to optimise number of columns. about rappel HOT 2 CLOSED

The relevant code is very straight forward and lives here for armv7: https://github.com/yrp604/rappel/blob/master/arch/armv7/display_armv7.c#L25-L45 (arm64 is nearly identical). The last argument to that function is the trailer when printing that register. As you should be able to see, it's currently grouped into blocks of four: tab, tab, tab, newline. If you were to split this into blocks of two (tab, newline, tab, newline) you'd get the desired behavior.

I don't think the phone use case is more popular than the desktop 80+ column terminal so I'm unlikely to change it across the board -- if you have any problems patching it please let me know.
