octeontx2-af: Fix potential integer overflows on integer shifts

[ Upstream commit 637c4f6fe40befa04f19c38b5d15429cbb9191d9 ]

The left shift int 32 bit integer constants 1 is evaluated using 32 bit
arithmetic and then assigned to a 64 bit unsigned integer. In the case
where the shift is 32 or more this can lead to an overflow. Avoid this
by shifting using the BIT_ULL macro instead.
