Revert "ACPI: resources: Add checks for ACPI IRQ override"
The commit 0ec4e55e9f57 ("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 0ec4e55e9f571f08970ed115ec0addc691eda613.
