fmd: Update range for FSL_FM_RX_EXTRA_HEADROOM
We need to reserve some space in the Rx skb buffer for NET_IP_ALIGN,
otherwise on forwarding the stack may reallocate the skb header.
The most easily available place to do this is the Rx extra headroom,
so enforce the minimum non-zero possible value as lower end of the
configuration range.
While here, enforce (and comment on) the restriction to only set values
which are a multiple of 16 bytes, which was missed in the previous
version of the help text.
