Falcon mode boots the kernel directly from SPL, without loading
the full U-Boot.
As pico-imx6ul 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.

There are two versions of imx6ul pico SOMs: one with 256MB and another
one with 512MB of RAM.
Convert to SPL so that both versions can be supported. This patch
doesn't rework the clock initialization to avoid changing the behavior
in this same patch, so it will be cleaned up in future.
Currently only the 256MB is tested/supported.
