imx_fec: Reserve full FSL_IMX25_FEC_SIZE page for the register file
...
Some i.MX SoCs (e.g. i.MX7) have FEC registers going as far as offset
0x614, so to avoid getting aborts when accessing those on QEMU, extend
the register file to cover FSL_IMX25_FEC_SIZE(16K) of address space
instead of just 1K.

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.

Add ENET/Gbps Ethernet support to FEC device
...
The ENET device (present in i.MX6) is "derived" from FEC and backward
compatible with it.
This patch adds the necessary support of the added feature in the ENET
device to allow Linux to use it (on supported processors).
