This patch adds non-DM version for mtk hsuart driver and makes it compatible with ns16550a driver in configuration. This is needed in SPL with CONFIG_SPL_DM disabled for reducing size.

All three UARTs of mt7628 are actually MediaTek's high-speed UARTs which support baudrate up to 921600. The high-speed UART is compatible with ns16550 when baudrate <= 115200.

Add compatible string to dtsi file so u-boot can use it when serial_mtk driver is built in.

The mt7621 spi controller supports continuous generic half-duplex spi transaction. There is no need to cache xfer data at all.

To achieve this goal, the OPADDR register must be used as the first data to be sent. And follows the eight generic DIDO registers. But one thing different between OPADDR and DIDO registers is OPADDR has a reversed byte order.

With this patch, any amount of data can be read/written in a single xfer function call.

This patch removes hardcoded gpio settings as they have been replaced by pinctrl in dts, and also replaces regmap-based phy reset with a more generic reset controller.

When received a packet with an invalid length recorded in rx descriptor, we should free this rx descriptor to allow us to continue to receive following packets. Without doing so, u-boot will stuck in a dead loop trying to process this invalid rx descriptor.

This patch adds a call to mt7628_eth_free_pkt() after received an invalid packet length.
