This makes the driver shift bits with BIT() which is used on other
places in the driver.

There is no in-kernel code using these indexed register
defines, and their offsets are clearly defined right below.
Cut them.

PL080S is a modified version of PL080 that can be found on Samsung SoCs,
such as S3C6400 and S3C6410.

It has different offset of CONFIG register, separate CONTROL1 register
that holds transfer size and larger maximum transfer size.

The header is used by drivers/dma/amba-pl08x.c, which can be compiled
under x86, where PL080 exists under a PCI-to-AMBA bridge. This patche
moves it where it can be accessed by other architectures, and fixes
all users.

The Nomadik PL080 variant has some extra protection bits that
may be set, so we need to check these bits to see if the
channels are actually available for the DMAengine to use.

<asm/hardware/pl080.h> doesn't have protection to deal with multiple inclusion.
And so we get compilation errors in cases where this file is included more than
once. This patch adds #ifdefs at the top of file to protect it against multiple
inclusions.

This PL008 among all other variables named PL080 doesn't seem
right. Fix it. Also add some missing defined that I use in the
new PL08x driver.

Add support for the DMA blocks in the S3C64XX series of CPUS,
which are based on the ARM PL080 PrimeCell system.

Unfortunately, these DMA controllers diverge from the PL080
design by adding another DMA controller register and
configuration for OneNAND.
