9d325f2341 [ARM] S3C: Update time initialisation to fix S3C64XX time problems
The S3C64XX timer is running at the wrong rate due to the
assumptions made in the timer initialisation about the way
the pwm dividers work. This means that time on the S3C64XX
runs twice as fast as it should.

Fix the problem by moving to using the clk framework to setup
the pwm timer clock muxes, as the pwm-clock code has all the
necessary knowledge of how the timer clock inputs are routed.

74b265d4e0 [ARM] S3C24XX: Move initialisation code to arch/arm/plat-s3c
We need to add plat-s3c to the build to get the headers
that will go in here once moved from include/asm-arm so
we may as well put some useful common s3c code in here
to stop the errors generated form having nothing built.

The cpu setup is now passed the cpu idcode and the table
of supported cpus to s3c_init_cpu() to abstract the
cpu identification out of the initial io setup.

As well as moving the cpu initialisation code, we move the
map of the board specific items up to the calling code as
none of the map_io() functions actually do anything other
than pass this to iotable_init().

This patch does not rename any of the init functions that
will be common to s3c24xx and any other s3c architectures
as this can be done at a later date as it will touch all
the board support files which use functions such as
s3c24xx_init_clocks() and s3c24xx_init_uarts().

Note, the header arch/arm/plat-s3c24xx/include/plat/cpu.h
still has functions that are used by both the cpu and
board initialisation functions. This means that each board
has definitions specific to the cpu support included and
the vice-versa.

dcea83adc6 [ARM] Hide ISA DMA API when ISA_DMA_API is unset
When ISA_DMA_API is unset, we're not implementing the ISA DMA API,
so there's no point in publishing the prototypes via asm/dma.h, nor
including the machine dependent parts of that API.

This allows us to remove a lot of mach/dma.h files which don't contain
any useful code.  Unfortunately though, some platforms put their own
private non-ISA definitions into mach/dma.h, so we leave these behind
and fix the appropriate #include statments.
