The pumpkin board is made by Gossamer Engineering and is using a MediaTek SoC. The board currently comes in two available version: MT8516 SoC and MT8167 SoC. The board provides the following IOs: eMMC, NAND, SD card, USB type-A, Ethernet, Wi-Fi, Bluetooth, Audio (jack out, 2 PDM port, 1 analog in), serial over USB, and an expansion header.
Additionally there is a HDMI port, DSI port, and camera port only on the MT8167 version of the board.
The board can be powered by battery and/or via a USB Type-C port and is using a PMIC MT6392.
The eMMC and NAND are sharing pins and cannot be used together.
This commit is adding the basic boot support for the Pumpkin MT8516 board on the eMMC.

V4: * Enable CONFIG_PINCONF in defconfig * Remove some bootargs related to UART in the environment.
V3: * Remove unused gd.
V2: * Set MTK_BROM_HEADER_INFO to 'emmc' since we only support eMMC right now.
