net: mvpp2: simplify MVPP2_PRS_RI_* definitions

Some of the MVPP2_PRS_RI_* definitions use the ~(value) syntax, which
doesn't compile nicely on 64-bit. Moreover, those definitions are in
fact unneeded, since they are always used in combination with a bit
mask that ensures only the appropriate bits are modified.

Therefore, such definitions should just be set to 0x0. In addition, as
suggested by Russell King, we change the _MASK definitions to also use
the BIT() macro so that it is clear they are related to the values
defined afterwards.

For example:

 #define MVPP2_PRS_RI_L2_CAST_MASK              0x600
 #define MVPP2_PRS_RI_L2_UCAST                  ~(BIT(9) | BIT(10))
 #define MVPP2_PRS_RI_L2_MCAST                  BIT(9)
 #define MVPP2_PRS_RI_L2_BCAST                  BIT(10)

becomes

 #define MVPP2_PRS_RI_L2_CAST_MASK              (BIT(9) | BIT(10))
 #define MVPP2_PRS_RI_L2_UCAST                  0x0
 #define MVPP2_PRS_RI_L2_MCAST                  BIT(9)
 #define MVPP2_PRS_RI_L2_BCAST                  BIT(10)

Because the values (MVPP2_PRS_RI_L2_UCAST, MVPP2_PRS_RI_L2_MCAST and
MVPP2_PRS_RI_L2_BCAST) are always applied with
MVPP2_PRS_RI_L2_CAST_MASK, and therefore there is no need for
MVPP2_PRS_RI_L2_UCAST to be defined as ~(BIT(9) | BIT(10)).

It fixes the following warnings when building the driver on a 64-bit
platform (which is not possible as of this commit, but will be enabled
in a follow-up commit):
