Reduce the access of the ESSR register. - makphyattach() have a code to detect the Fiber/Copper auto selection feature. Save the info to sc_flags to reduce the access to the ESSR register. One of the reason is that the register is not implemented on QEMU. Another reason is that it's not required to access the register if the device is in the copper only mode.

- 88E1000(S) has no page select register, so don't access it. Note that qemu doesn't implement the register and the access fails. For I210, we can use the register. - Don't set PSCR_CRS_ON_TX bit on I210.
