[PATCH v3 2/4] irqchip/qcom-pdc: Switch to using IRQCHIP_PLATFORM_DRIVER helper macros

Switch the driver to use the helper macros. In addition to reducing the number of lines, this also adds module unload protection (if the driver is compiled as a module) by switching from module_platform_driver to builtin_platform_driver.
