fno-jump-tables isn't enough to guard against
gcc switch optimizations that are unsafe to use
in code that runs before relocation.
The switch-tree-conversion opt pass may generate
lookup tables that are placed in the data section

prior to relocation.

The current implementation fakes a memory-mapped I/O device
at 0x3f8 and 0x2f8, then uses platform read/write functions
to do the actual reading and writing. These platform functions
only exist for the x86 platform; better to move the I/O
routines into the driver and have the driver request I/O ports
using request_ioport_region.

The board code does a phy reset. This implicitly requests the phy reset
gpio. This gpio is also registered in the devicetree as phy reset gpio,
so the fec driver probe can't request the gpio and bails out with -EBUSY.
Fix this by freeing the phy reset gpio in the board code. While at it use
gpio_request_array for the gpios.

TX_CLK line is approx. 54mm longer than other TX lines which adds
a delay of 0.36ns. RGMII need a delay of min. 1.0ns. This mean we have to add
a delay of 0.64ns. We choose 0.78 to have a little gap. This can be done by
setting GTX pad skew value to 11100
Also add a delay for the RX delay lines, needed for the Duallite variant.
=> Set register 2.8 (RGMII Clock Pad Skew) to 0x039F.
