Improve the README by adding instructions on how to boot using
Falcon mode, which allows the SPL to load the kernel directly,
without using U-Boot proper.

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.
