net/mlx5: Convert scaled ppm values outside the s32 range for PHC frequency adjustments
Represent scaled ppm as ppb to the device when the value in scaled ppm is
not representable as a 32-bit signed integer. mlx5 devices only support a
32-bit field for the frequency adjustment value in units of either scaled
ppm or ppb.
Since mlx5 devices only support a 32-bit field for the frequency adjustment
value independent of unit used, limit the maximum frequency adjustment to
S32_MAX ppb.
