net: mvpp2: fix RSS register definitions
There is no RSS_TABLE register in PPv2 Controller. The register 0x1510 which was specified is actually named "RSS_HASH_SEL", but isn't used by this driver at all. Based on how this register was used, it should have been the RXQ2RSS_TABLE register, which allows to select the RSS table that will be used for the incoming packet. The RSS_TABLE_POINTER is actually a field of this RXQ2RSS_TABLE register. Since RSS tables are actually not used by the driver for now, this commit does not fix a runtime bug.
