irqchip: Revert modular support for drivers using IRQCHIP_PLATFORM_DRIVER helperse
It has become obvious that switching a number of irqchip drivers to being platform drivers without considering the platform was a mistake. We have multiple reports of end-point drivers not probing because the irqchip driver isn't there yet, breaking the expectations of the users.
This patch reverts:
920ecb8c35cb ("irqchip/mtk-cirq: Convert to a platform driver") f97dbf48ca43 ("irqchip/mtk-sysirq: Convert to a platform driver") 5be57099d445 ("irqchip/qcom-pdc: Switch to using IRQCHIP_PLATFORM_DRIVER helper macros") 95bf9305d2e3 ("irqchip/qcom-pdc: Allow QCOM_PDC to be loadable as a permanent module")
and leave QCOM PDC, MTK sysrq and cirq drivers as built-in, special purpose drivers for the time being until we have worked out a better solution.

irqchip: mtk-sysirq: Get irq number from register resource size
Originally mtk-sysirq hardcoded supported irq number to 224. This was fine since all SoCs before support the same number of irqs for intpol.
However MT8173 intpol support 32 more irq pins, changes to get irq number from register resource size to suppor MT8173 properly.

irqchip: mtk-sysirq: Use IS_ERR() instead of NULL pointer check
Beniamino noticed a bug that an invalid DT file for the mediatek interrupt polarity extension will cause kernel oops.
The reason is that the interrupt polarity support for mediatek chips merely checks for NULL pointer instead of a casted error return value in mtk_sysirq_of_init() so any other casted error value passes the NULL pointer check and causes a kernel panic when dereferenced.
Use IS_ERR() and return the error value via PTR_ERR().
[ jac: took V2 over V3 for diff formatting, hand-added V3 changes, tweaked subject line. ]
