serial: 8250: omap: Move uart_write() inside PM section
Commit Message
If CONFIG_PM is not set (e.g. m68k/allmodconfig):
drivers/tty/serial/8250/8250_omap.c:169:13: error: ‘uart_write’ defined but not used [-Werror=unused-function]
169 | static void uart_write(struct omap8250_priv *priv, u32 reg, u32 val)
| ^~~~~~~~~~
Fix tis by moving uart_write() inside the existing section protected
by #ifdef CONFIG_PM.
