crypto: amcc - convert irq_of_parse_and_map to platform_get_irq

Browse Source 
Replace the deprecated irq_of_parse_and_map() call with the modern
platform_get_irq() in the probe function. This also improves error
handling: platform_get_irq() returns a negative errno on failure,
whereas irq_of_parse_and_map() returned 0.

Change the irq field in struct crypto4xx_core_device from u32 to int
to match the return type of platform_get_irq().
