TI K3 devices (J721E, J721S2, AM62X .etc) have the same variant
of UART as OMAP4. Add the compatible used in Linux device tree,
"ti,am654-uart" to the OMAP UART dt_match so that the driver can
be used with these devices. Also, enable the driver for ARM64
platforms.

This selects the Texas Instruments OMAP UART. If you have a Texas
Instruments based CPU, say Y.
