fsl/fman: Validate cell-index value obtained from Device Tree
[ Upstream commit bd50c4125c98bd1a86f8e514872159700a9c678c ]
Cell-index value is obtained from Device Tree and then used to calculate
the index for accessing arrays port_mfl[], mac_mfl[] and intr_mng[].
In case of broken DT due to any error cell-index can contain any value
and it is possible to go beyond the array boundaries which can lead
at least to memory corruption.
Validate cell-index value obtained from Device Tree.
