Set up some IRQ space to allocation to off-SoC interrupt controllers.
Default this to 16 IRQs. If individual boards require more than this
then they will need to modify this file so allocating a small number
helps reduce the number of modifications required.

Correct the lli structure in struct s3c64xx_dma_buff which should

version 'struct pl080_lli'

A few typos seems to have sneaked into the HCLK gate defines, causing the
usb host clock to not get enabled. Fix them according to the reference
manual and throw in the 3d accel bit for good measure.

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.

Cleanup arm/plat-s3c64xx/include/plat/gpio-bank-h.h include file.
Using shift-left operation with value >32 is a bad habit.
