arm64: dts: qcom: sdm845: narrow LLCC address space

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.
