spi: spi-mpc52xx: use platform_get_irq_optional for IRQ lookup

Browse source

Replace irq_of_parse_and_map() calls with platform_get_irq_optional()
to fetch both IRQs in the probe function. This is a more portable
approach that works with both DT and non-DT platforms and follows
modern platform API conventions.

The -EPROBE_DEFER case is handled properly so deferred probe works
as expected, and invalid IRQ numbers are normalized to 0.
