[ Upstream commit 300b5f661eebefb8571841b78091343eb87eca54 ]
The Last Level Cache Controller (LLCC) device does not need to access
entire LLCC address space. Currently driver uses only hardware info and
status registers which both reside in LLCC0_COMMON range (offset
0x30000, size 0x1000). Narrow the address space to allow binding other
drivers to rest of LLCC address space.
