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. While at it, let's also fix the size of the llcc_broadcast_base to cover the whole region. 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.
