drm/nouveau/gpio: enable interrupts on cards with 32 gpio lines

The code attempts to enable them, but hits an undefined behaviour by
shifting by the entire register's width:

    int lines = 32;
    u32 mask = (1 << lines) - 1;    // 00000000 on x86
    u32 mask = (1 << lines) - 1;    // ffffffff on arm (32)
    u32 mask = (1 << lines) - 1;    // 00000000 on arm64
    u32 mask = (1ULL << lines) - 1; // ffffffff everywhere
