I'm not so familiar with how things work with Qualcomm, but in general
I think putting this in the "board" file is a bad idea. I'd be OK
with putting this directly in the SoC file (though it might get
unwieldy?), but not moving things to the board file as was done with
v2 of this patch.
Said another way: nearly board that uses SDM845 that uses UART2 will
have the same definitions for these pins so we shouldn't be
duplicating it across every board, right?
I'll also respond to the v2 patch so it's obvious there is feedback there...
