Subject: [PATCH net v3 2/2] net: phy: aquantia: remove usage of phy_set_max_speed
Remove the use of phy_set_max_speed in phy driver as the
function is mainly used in MAC driver to set the max
speed.
Instead use get_features to fix up Phy PMA capabilities for
AQR111, AQR111B0, AQR114C and AQCS109
Fixes: 038ba1dc4e54 ("net: phy: aquantia: add AQR111 and AQR111B0 PHY ID")
Fixes: 0974f1f03b07 ("net: phy: aquantia: remove false 5G and 10G speed ability for AQCS109")
Fixes: c278ec644377 ("net: phy: aquantia: add support for AQR114C PHY ID")

Changes since v2
1. seperate out the changes into two different patches.
2. remove usage of phy_set_max_speed from the aquantia driver
3. use phy_gbit_features instead of initializing each and
every link mode bits.
4. write seperate functions for 5Gbps supported phy
5. remove FIBRE bit which was introduced in patch 1
Changes since v1
1. remove usage of phy_set_max_speed in the aquantia driver code.
2. Introduce aqr_custom_get_feature which checks for the phy id and
takes necessary actions based on max_speed supported by the phy
3. remove aqr111_config_init as it is just a wrapper function.
