drivers: char: Enable OMAP UART driver for TI K3 devices

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.
