uart_write() was introduced as a helper function that is for now only
used in omap8250_soft_reset(). The latter function is only defined if
CONFIG_PM is enabled. So add __maybe_unused to the defintion of the
former function to fix
drivers/tty/serial/8250/8250_omap.c:169:13: error: ‘uart_write’ defined but not used [-Werror=unused-function]
for CONFIG_PM=n builds.
Fixes: 398cecc24846 ("serial: 8250: omap: Fix imprecise external abort for omap_8250_pm()")
