Reading the link state via PHYSTS was incorrect, as it only reflects the
link state bit from BMSR. BMSR latches link down events, and are not
cleared without being read. (See 802.3-2008 section 2, section 22.2.4.2.13)
This leads to the original DP828xx code only supporting link up, then a
single link down event.
Switch to reading the link state via BMSR, but continuing to read the
negotiation results via PHYSTS and ANLPAR. This is inline with
LAN8720x, RTL8201, KSZ80xx phy drivers, and other opensource drivers for
the DP838xx family of devices.
Tested on a private board with a DP83825i PHY. No publically available
boards using the original DP83848 are known of for testing.

In esp_eth_test_apps.c:
Add test of loopback functionality. Change speed/duplex/autonegotiation test - remove need to enable loopback (required
for it to work on some phys supported by ESP-IDF)
In Kconfig.projbuild:
Add parameters to select which configuration is used - standard or custom.
Add for custom configuration parameters to select MDC and MDIO pins (required to work with WESP-32 and other boards that
use non-standard pin assignments).
In esp_eth_test_common.c:
Add code to support changes made in Kconfig
In sdkconfig.ci.default_rtl8201:
Change config which is used. Now custom is used and MDC is gpio 16, MDIO is gpio 17. Reuqired to work with WESP-32
In esp_eth_phy_802_3.h:
Make 802.3 API public.
In esp_eth_phy_802_3.c:
Add loopback check in eth_phy_802_3_set_duplex(). Now ESP_ERR_INVALID_STATE is invoked on attempt to set duplex to half
when loopback is enabled.
Remove static property from esp_eth_phy_802_3_autonego_ctrl and esp_eth_phy_802_3_loopback.
In esp_eth_phy_dm9051.c:
Add dm9051_loopback() because DM9051 requires setting additional bit to enable auto-negotiation loopback for data to be
received. Add dm9051_set_speed() which invokes ESP_ERR_INVALID_STATE on attempt to set speed to 10 Mbps when loopback is
enabled because such speed configuration is unsupported.
In esp_eth_phy_ksz80xx.c:
Add ksz80xx_set_speed() which invokes ESP_ERR_INVALID_STATE on attempt to set speed to 10 Mbps when loopback is enabled
because such speed configuration is unsupported.
In esp_eth_phy_ksz8851snl.c:
Change phy_ksz8851_set_duplex() to invoke ESP_ERR_INVALID_STATE on attempt to set duplex to half when loopback is enabled.
In esp_eth_phy_dp83848.c, esp_eth_phy_rtl8201.c:
Add autonego_ctrl implementation which prevents enabling autonegotiation when loopback is enabled.
Add loopback implementation which disables autonegotiation prior to enabling loopback.
In esp_eth_phy_lan87xx.c:
Add autonego_ctrl implementation which prevents enabling autonegotiation when loopback is enabled.
Add loopback implementation which disables autonegotiation prior to enabling loopback.
Fix link indicating being down when loopback is enabled by force setting link up.
Use Root certificate (`DigiCert Global Root G2`) for the
`dl.espressif.com` and `espressif.com` test endpoints.
This fixes the test failure introduced due to renewal of
the intermediate certificate.
