9f364a13c6 Increase button delays in preperation for frequency scaling. 
When run at lower clock speeds, delays seem to need to be a little
longer in absolute time.

281d1fadb3 Do not include kernel.h in system.h. 
system.h doesn't need it on its own and this change makes it less
dependant on Rockbox internals.

307cb04948 AS3525v1/2: Enable nested handling of interrupts 
Mostly for the sake of reducing latency for audio servicing where other service
routines can take a long time to complete, leading to occasional drops of a
few samples, especially in recording, where they are fairly frequent.

One mystery that remains is GPIOA IRQ being interrupted causes strange
undefined instruction exceptions, most easily produced on my Fuze V2 with a
scrollwheel. Making GPIOA the top ISR for now, thus not interruptible, cures it.

SVC mode is used during the actual calls. Hopefully the SVC stack size is
sufficient. Prologue and epilogue code only uses the IRQ stack and is large
enough.

Any routine code that should not be interrupted should disable IRQ itself from
here on in.

845af676f8 as3525(v2): Add a somewhat inaccurate udelay (-0.5/+1.0µs). It should work good for some huge delays. 
Use it in fuzev2 to improve some big delays (correct the biggest one to actually wait for the fifo to empty), and use it in the sd drivers.
