gpio: em: Use irq_domain_add_simple() to fix runtime error



Adjust the gpio-em.c driver to reconsider the pdata->irq_base
variable. Non-DT board code like for instance board-kzm9d.c
needs to operate of a static IRQ range for platform devices.

So this patch is updating the code to make use of the function
irq_domain_add_simple() instead of irq_domain_add_linear().

Fixes a EMEV2 / KZM9D runtime error caused by the following commit:
7385500a gpio/em: convert to linear IRQ domain
