mb/asrock/h110m: set serirq_mode to continuous mode
By default, the LPC SIRQ mode is set to Quiet mode. Therefore, COM-port
from the SurerIO chip don't work correctly after the LPC controller (PCI
0:1f.0) initialization. Console output is broken. The patch fixes this
bug by overriding the serirq_mode option in the devicetree.cb to set
Continuous SIRQ mode
