This patch adds xgene_enet_check_phy_hanlde() function that checks whether
MDIO driver is probed successfully and sets pdata->mdio_driver to true.
If MDIO driver is not probed, ethernet driver falls back to backward
compatibility mode.
Since enum xgene_enet_cmd is used by MDIO driver, removing this from
ethernet driver.

This patch fixes clock reset sequence.
- Added clock reset sequence for ACPI
- Added delay in clock reset sequence to make sure pulse is generated
- Added clk_unprepare_disable() in port shutdown to make sure
clock increment/decrement counts are matching
- Removed MII_MGMT_CONFIG programming, since it is not required
- Fixed programming XGENET_CONFIG_REG to enable SGMII mode

When the driver is configured as kernel module and when it gets
unloaded and reloaded, kernel crash was observed. This patch
address the hardware resource cleanups by doing the following,
- Added mac_ops->clear() to do prefetch buffer clean up
- Fixed delete freepool buffers logic
- Reordered mac_enable and mac_disable
- Added Tx completion ring free
- Moved down delete_desc_rings after ring cleanup

Since mac_init is too heavy to be called when the link changes,
moved the speed_set configuration to a new function and added
mac_ops->set_speed function pointer. This function will be
called from adjust_link callback.
Added cases for 10/100 support for SGMII based 1G interface.
