+ The FIQ serial debugger can accept commands even when the

+ Enables the serial debugger at boot. Passing

+ Don't disable the wakeup irq when enabling the uart clock. This will
+ cause extra interrupts, but it makes the serial debugger usable with
+ on some MSM radio builds that ignore the uart clock request in power
+ collapse.
