Not that I know :-)

If what it means is a number of registers from address x thru x+n
words in memory that is called a register range usually, the
Device Tree "regs" property.

If you're referring to a subset of registers dealing with a batch
of pins or a single pin that can use whatever terminology you
want, I consider it a driver-internal detail. Some GPIO drivers
talk about "ports" when they have e.g. 2 x 32bit registers
handling a total of 64 pins, then that is port 0 and port 1 or
something like this, but it's really up to the driver.
