northbridge/amd/pi/northbridge.c: Remove superfluous logic operand
The "((1ull << (sizeof(modules) * 8)) - 1)" statement evaluates to
0xffffffff, but there's no need to AND with that value, as 'modules'
is already 32-bit. The '&&' is most likely a typo, which meant bitwise
and, as indicated by the structure of thus operation.
Remove this superfluous statement. This also fixes a clang warning.
