[PATCH] x86: remove superfluous dmi_ignore_irq0_timer_override quirks

[Andreas Herrmann <andreas.herrmann3@amd.com>]

The problem should be solved with commits:

x86: SB600: skip IRQ0 override if it is not routed to INT2 of IOAPIC
x86: SB450: skip IRQ0 override if it is not routed to INT2 of IOAPIC

IMHO it does not make sense to check within a dmi-quirk
whether an early-quirk was applied. Boot sequence is as follows:

acpi_boot_table_init()   (it applies dmi-quirks)
...
early_quirks()           (detect bogus IRQ0 override)
...
acpi_boot_init()         (setup IO APIC)

Thus with current code we will always get following warnings for
Laptops that have this dmi_ignore_irq0_timer_override dmi quirk:

  WARNING: at arch/x86/kernel/acpi/boot.c:1410
  dmi_ignore_irq0_timer_override+0x30/0x60()
  ati_ixp4x0 quirk not complete.

... just because the early-quirk (ati_ixp4x0) was not yet executed.
