(cherry picked from commit a1037f203c6a07cb116eeb1632cb7200ad022cd3)

This cherry-pick was modified to match the tegra124 uart.c, which
uses the idx and base address calculations instead of Kconfig settings.
This driver could use the 8250MEM driver when the ARM vs x86 IO
calling convention is worked out.
