common/mlx5: remove redundant spaces in PRM header

File drivers/common/mlx5/mlx5_prm.h includes structs representing
data items as defined in PRM document.
Some of these structs were copied as-is from kernel file mlx5_ifc.h.
As result the structs are not all aligned with the same spacing.

This patch removes redundant spaces and new lines from several structs,
to align all structs in mlx5_prm.h to the same format.
