pico-imx7d: Add SPL support
Convert pico-imx7d to SPL support.
There are two variants of pico-imx7d SOMs:
- One with 512MB of RAM
- One with 1GB of RAM
The 512MB module contains two Hynix H5TC2G63GFR-PBA.
The 1GB module contains two Hynix H5TC4G63GFR-PBA.
The RAM size is determined in runtime by reading GPIO1_12.
While at it, also add USB Serial Download mode support as it
is very helpful for loading SPL and u-boot.img via imx_usb_loader.
