The PHY power up/down pin is attached to GPIO port H on the EP9302.  You 
have to set the data-direction-register for that bit to 'b1 and then write 
to the data-register a 'b0 to that bit.  i.e.

#define PHDDR   0x80840044
#define PHDR    0x80840040

// Turn off PHY
POKE32(PHDDR, 0x4);
POKE32(PHDR, 0x0);

To do this from userspace, you'll have to mmap the /dev/mem device.  You'll 
want to mmap at 0x80840000 offset since you can only mmap on page 
boundaries.
