This patch adds uart support for MediaTek MT7620 and earlier SoCs.
The UART used by MT7620 is incompatible with the ns16550a driver.
All registers of this UART have different addresses. A special 16-bit
register for Divisor Latch is used to set the baudrate instead of the
original two 8-bit registers (DLL and DLM).
The driver supports of-platdata which is useful for tiny SPL.

This patch converts the dart6ul ethernet support to DM_ETH and cleans
up the legacy ethernet code. The clean up, more specifically:
* moves the fec2 node and pin definition to the carrier board DTS
since the phy associated with it is on the carrier board and not on
the SoM;
* add the reset pin associated to each phy;
* separate the ethernet, mdio and reset pins of each fec so that they
are easier to reference;
* add clock properties to the phy nodes since they are connected to the
50Mhz ENET[12]_TX_CLK clock of the SoC;
* remove CONFIG_BOARD_EARLY_INIT_F since the function is now empty.

This fixes eth0 not initializing properly. Both eth0 and eth1 use the
MDIO interface on eth1 to access their PHYs. However, without
DM_ETH_PHY, eth0 still tries to use its own MDIO interface to access its
phy. Before this patch, a boot log might contain lines like
Net:
Warning: ethernet@20b4000 using MAC address from ROM
eth1: ethernet@20b4000 [PRIME]Could not get PHY for FEC0: addr 2
After this patch they now look like
Net:
Warning: ethernet@20b4000 using MAC address from ROM
eth1: ethernet@20b4000 [PRIME]Get shared mii bus on ethernet@2188000
Warning: ethernet@2188000 using MAC address from ROM
