The offset parameter in the devres devm_ioremap_*() functions kerneldoc
entries is erroneously defined as BUS offset whereas it is actually a
resource address.

Since it is actually misleading, fix the devres devm_ioremap_* offset
parameter kerneldoc entry by replacing BUS offset with a more suitable
description (ie Resource address).
