Subject: [PATCH] Support termios for Tiva

The lower-half serial driver for Tiva (TI TM4C12x) microcontrollers supports
termios, but Kconfig never enabled this support because we were missing the
ARCH_HAVE_SERIAL_TERMIOS configs. This is now enabled, allowing termios support
to be enabled with CONFIG_SERIAL_TERMIOS.

* arch/arm/src/tiva/Kconfig
  (config TIVA_UART0 thru TIVA_UART7): Select ARCH_HAVE_SERIAL_TERMIOS.
