qcacmn: Allocate lut based on number of DBR entry

CFR component allocate 140 luts but some of platform use 48 of them,
which allocate huge memory at one time and waste memory in some
platform. In low memory case, it may be failed to alloc luts at one
time. So, allocate lut based on number of DBR entry and split memory
allocation.
