Revert "ACPI: resources: Add checks for ACPI IRQ override"

The commit 419279200735 ("ACPI: resources: Add checks for ACPI IRQ
override") introduces regression on some platforms, at least it makes
the UART can't get correct irq setting on two different platforms,
and it makes the kernel can't bootup on these two platforms.

This reverts commit 4192792007353dbeb94d533bee0216daf49928df.
