011a78c194 gpio: sifive: Set affinity callback to parent 
This assigns the .irq_set_affinity to the parent callback.
I assume the sifive GPIO can be used in systems with
SMP.

I used the pattern making the hirerarchy tolerant for missing
parent as in Marc's earlier patches.

f52d6d8b43 gpio: sifive: To get gpio irq offset from device tree data 
We can get hwirq number of the gpio by its irq_data->hwirq so that we don't
need to add more macros for different platforms. This patch is tested in
SiFive Unleashed board and SiFive Unmatched board.

b72de3ff19 gpio: sifive: Fix SiFive gpio probe 
Fix the check on the number of IRQs to allow up to the maximum (32)
instead of only the maximum minus one.

a924eae751 gpio: sifive: fix static checker warning 
Typcasting "irq_state" leads to the below static checker warning:
The fix is to declare "irq_state" as unsigned long instead of u32.

	drivers/gpio/gpio-sifive.c:97 sifive_gpio_irq_enable()
	warn: passing casted pointer '&chip->irq_state' to
	'assign_bit()' 32 vs 64.
