imx_fec: Use ENET_FTRL to determine truncation length
Frame truncation length, TRUNC_FL, is determined by the contents of
ENET_FTRL register, so convert the code to use it instead of a
hardcoded constant.
To avoid the case where TRUNC_FL is greater that ENET_MAX_FRAME_SIZE,
increase the value of the latter to its theoretical maximum of 16K.
