lib: sbi_irqchip: Allow interrupt client to specify line sensing

Browse Source 
The interrupt client should be allowed to specify the line sensing
type of the hwirqs for which it is registering handler. To support
this, add hwirq_flags parameter to hwirq_setup() callback provided
by the irqchip driver.
