recipes-ti: Add recipe and patches for jailhouse support for am62xx

Add and enable Jailhouse support for TI's k3-am625-sk similarly to how other
TI platforms were added and enabled in the past by adding platform-specific
configuration variables for the root cell DTB overlay, and the Linux demo inmate
DTB, configuration, and Kernel command line settings.

Migrate the jailhouse recipe to kirkstone from dunfell.

Switch to latest upstream source tree for jailhouse. The TI Jailhouse repo has
gone stale and now upstream is really the happening place where new development
happens including for new devices such as AM62x. Hence go ahead and switch to
using the upstream repo.

Update the platform-specific config files to such that the root cell DTB overlay
gets included in the file system images.

Enable additional console on ttyS3 (usually mapped to main_uart1) and ttyS2 for
the Linux demo inmate to use.

Add patches for the Jailhouse source tree for am62xx.
