I don't think these defines were ever used.  At any rate, we have common
bit defines for all parts as well as a Kconfig option to declare the EBIU
async timings, and no one has really complained about this so far.

Since we always use these ids as unsigned values, and we have some assert
code to make sure they don't exceed a limit, avoid signed issues.

If we're double faulting, then we have to assume the VMAs are not safe as
broken pointers here will prevent full trace output for the double fault.
Shouldn't be a big problem though as rarely is a double fault caused by
code in userspace.

The DMA channel status field was encoding redundant info wrt the DMA MMR
config register, and it was doing an incomplete job of checking all DMA
channels (some drivers write directly to the config register).  So drop
the tristate field in favor of a binary atomic field.  This simplifies
the code in general, removes the implicit need for sleeping, and forces
the suspend code to handle all channels properly.

The GPIOs on ports C/D/E on the BF538/BF539 do not behave the same way as
the other ports on the part and the same way as all other Blackfin parts.
The MMRs are programmed slightly different and they cannot be used to
generate interrupts or wakeup a sleeping system.  Since these guys don't
fit into the existing code, create a simple gpiolib driver for them.

PLL_LOCKCNT applies only to the PLL programming sequence which does not
apply to core and system clock dividers.  Writes to PLL_DIV to change the
CSEL/SSEL dividers take effect immediately.

There is still overhead in software in writing the new dividers, so just
use a value of 50us as this should be good enough.
