soc/intel/braswell: Correct serial IRQ support
Serial IRQ was configured in quiet mode, but not enabled.
Enable serial IRQ and use 'enum seriirq_mode' as a devicetree
option.
Function sc_enable_serial_irqs() is added to enabled serial IRQs.
enable_serirq_quiet_mode() is renamed to
sc_set_serial_irqs_mode(). This function use the 'serirq_mode' to
set the mode. The call to this function is moved from finalize to init
having serial IRQs enable in early stage.
Serial IRQs must be enabled in continuous mode for at least one frame
before switching into quiet mode.
BUG=N/A
TEST=Portwell PQ7-M107
