ipmi: si: Use platform_get_irq_optional() to retrieve interrupt

Browse Source 
Use platform_get_irq_optional() to retrieve the interrupt resource
instead of directly parsing and mapping the OF node via
irq_of_parse_and_map().  This is the standard pattern for platform
devices.  irq_of_parse_and_map() requires ire_dispose_mapping(), which
is missing.

[Handle a negative return from platform_get_irq_optional() to mean
 no interrupt is assigned.]
