Revert "phy: add support for a reset-gpio specification"
Commit da47b4572056 ("phy: add support for a reset-gpio specification")
causes the following xtensa qemu crash according to Guenter Roeck:
[ 9.366256] libphy: ethoc-mdio: probed
[ 9.367389] (null): could not attach to PHY
[ 9.368555] (null): failed to probe MDIO bus
[ 9.371540] Unable to handle kernel paging request at virtual address 0000001c
[ 9.371540] pc = d0320926, ra = 903209d1
[ 9.375358] Oops: sig: 11 [#1]
This reverts commit da47b4572056487fd7941c26f73b3e8815ff712a.
