fsp_broadwell_de: Add Kconfig switch for SERIRQ operation mode
The serial IRQ (SERIRQ) used by the LPC interface can operate either in
continuous or in quiet mode. Add a Kconfig switch to select the desired
mode. This switch can now be used on mainboard level to enable the
needed mode per mainboard.
