The addrmap5 value is the same for the 512MB and 1GB variants,
so there is no need to override it.

Falcon mode boots the kernel directly from SPL, without loading
the full U-Boot.
As pico-imx7d does not have a GPIO for selecting Falcon versus
normal mode, enter in Falcon mode when the customer selects
the CONFIG_SPL_OS_BOOT option in menuconfig.

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.
