Subject: [PATCH 4/7] devlink: Adding perm config of link settings

Extending DEVLINK_ATTR_PERM_CFG (permanent/NVRAM device configuration)
to include persistent configuration of device link settings:

DEVLINK_ATTR_PERM_CFG_AUTONEG_PROTOCOL: Configure default autoneg
protocol; use enum devlink_autoneg_protocol.

DEVLINK_ATTR_PERM_CFG_MEDIA_AUTO_DETECT: Configure default
auto-detection of attached media connector (1 = enable, 0 =
disable).

DEVLINK_ATTR_PERM_CFG_PHY_SELECT: Configure default external PHY
selection (0 = PHY 0, 1 = PHY 1).

DEVLINK_ATTR_PERM_CFG_PRE_OS_LINK_SPEED_D0: Configure default
pre-OS link speed in full power (D0) state; use enum
devlink_pre_os_link_speed.

DEVLINK_ATTR_PERM_CFG_PRE_OS_LINK_SPEED_D3: Configure default
pre-OS link speed in sleep (D3) state; use enum
devlink_pre_os_link_speed.
