AM642 allows for booting from primary or backup boot media.
Both media can be chosen individually based on switch settings.
ROM looks for a valid image in primary boot media, if not found
then looks in backup boot media. In order to pass this boot media
information to boot loader, ROM stores a value at a particular
address. Add support for reading this information and determining
the boot media correctly.

Starting J7200 SoC, ROM supports for loading sysfw directly from boot
image. ROM passes this information on number of images that are loaded
to bootloader at certain location. Add support for storing this
information before it gets corrupted.

Add an api soc_is_j721e(), and use it to enable certain functionality
that is available only on j721e. This detection is needed when DT is not
available.

JTAG ID register is defined by IEEE 1149.1 for device identification.
Use this JTAG ID register for identifying AM65x[0] and J721E[1] devices
instead of using SoC specific registers.
