[PATCH] drivers: char: Enable OMAP UART driver for TI K3 devices

[Vaishnav Achath <vaishnav.a@xxxxxx>]

TI K3 devices (J721E, J721S2, AM62X .etc) has 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.
