The LLCC block has several banks each with a different base address
and holes in between. So it is not a correct approach to cover these
banks with a single offset/size. Instead, the individual bank's base
address needs to be specified in devicetree with the exact size.

Also, let's get rid of reg-names property as it is not needed anymore.
The driver is expected to parse the reg field based on index to get the
addresses of each LLCC banks.
