MDO - HWA vbusm2ram sniffer address allocation logic is incorrect

Details

For MDO, while sniffing the 128 kB HWA memory, the address allocation for sniffer logic is incorrect, since the address is translated by 512 kB whenever 32kB boundary is crossed:

0 -32KB no translation
32KB-64KB address is translated by 512KB [22:19] = [18:15]
64KB-96KB address is translated by 512KB [22:19] = [18:15]
96KB to 128KB address is translated by 512KB [22:19] = [18:15]

Workaround

While programming the address, snif_waddr[18:15] must be the same as snif_waddr[22:19].
