ITE: drivers/serial: add the UART driver for the PM callback function

Browse source 
IT8XXX2 uses shared ns16550.c driver which does not provide a power
management callback(pm_action_cb), so create driver to handle
IT8XXX2 specific UART features.

note: pm_action_cb(old name: pm_control_fn)

bool "ITE IT8XXX2 UART driver"
help
IT8XXX2 uses shared ns16550.c driver which does not
provide a power management callback, so create driver
to handle IT8XXX2 specific UART features. In addition
to use pm_action_cb, we also need to make some setting
at uart_it8xxx2_init.
