mmc: omap_hsmmc: use platform_get_irq_optional for wake IRQ
Replace irq_of_parse_and_map() with platform_get_irq_optional() to
get the wake IRQ. This is a more portable approach that works with
both DT and non-DT platforms, and follows the modern platform API
conventions for optional IRQ resources.
The wake IRQ is now fetched earlier in the probe function alongside
the main IRQ, and the -EPROBE_DEFER case is handled properly before
the deferred probe can be triggered.
