qcacmn: Support none 4k page size kernel

DP uses multi page allocation for tx/rx descriptor.
ID and offset mask of decriptor is based on 4096 which
couples with Kernel's MMU PAGE_SIZE. This cause trouble
when deploy driver on none-4K page size kernel.
Set qdf_dp_blockmem_size to 4096 so that DP won't
depend on kernel page size.
