c9c1349773 usb-s3c6400: merge the 2 drivers
Player-specific code remaining: usb_drv_(init,exit)

The iPods lack a MMU, so:
    - physical, virtual, and uncached addresses are identical
    - since we can't access uncached memory we discard caches when receiving data

Still not quite reliable on nano2g

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.

184459fa54 Deal with a complication when transferring recording method from PP5024: since the FIFO POP is always read until empty, keep track of sample parity instead of always saving the first one in the FIFO upon entering the ISR or else the first of a duplicate that is also the last in the FIFO would get duplicated. Also, give top priority to audio interrupts in all cases.

c196da2cee FS#11597 : decrease FCLK frequency when unboosted
FCLK is unused because we use fastbus clocking: CPU clock = PCLK
Base PCLK off PLLA and use the lowest frqeuency for FCLK (24MHz source,
maximum divider)
Save a bit of power, adjust Clipv1/e200v2/Fuzev1 current usage accordingly

Note: the power saving (in mA) is a bit less on e200v2/Fuzev1 than on Clipv1
