platform/x86: quickstart: Fix race condition when reporting input event
Since commit e2ffcda16290 ("ACPI: OSL: Allow Notify () handlers to run
on all CPUs"), the ACPI core allows multiple notify calls to be active
at the same time. This means that two instances of quickstart_notify()
running at the same time can mess which each others input sequences.
Fix this by protecting the input sequence with a mutex.
Compile-tested only.
