f6432ecea6 pico-imx6ul: Provide a way to escape the Falcon mode
When CONFIG_SPL_OS_BOOT is selected, it is still convenient to be able
to escape from Falcon mode and boot to U-Boot proper.

Add a mechanism that allows booting in U-Boot proper when the
key 'c' is entered on console at boot time.

9b8d9ec41a pico-imx6ul: Fix eMMC boot after DM_MMC conversion
After the DM_MMC conversion the following eMMC boot error is observed:

U-Boot SPL 2019.04-rc4 (Mar 20 2019 - 18:53:28 +0000)
Trying to boot from MMC1
MMC Device 0 not found
spl: could not find mmc device 0. error: -19
SPL: failed to boot from all boot devices
### ERROR ### Please RESET the board ###

This happens because the SPL code does not initialize the SDHC pins
and clock.

Fix it by moving the original eMMC initialization from U-Boot proper
to SPL.

9ddd1cd596 pico-imx6ul: Add Falcon mode support
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.

82a8a93327 pico-imx6ul: Convert to SPL
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.
