It doesn't buy us anything in here, but it's conceivable that someone

It wouldn't be IDE driver then, and neither it would be libata which
also does this another way this (despite pata_platform uses shifts too
-- not in the accessors, so no speed loss).
The device tree is not just for Linux.
equivalent of the cntlzw innstruction, and shift makes it clear that
the stride must be power-of-two). Plus, using shift is consistent
with what we do on ns16550.
Why the heck should we care about the UART code taling about IDE?!
Consistency?
So, let me consider your argument purely speculative and invalid. ;-)
Consider it whatever you want. :-)
