The idma_reg_addr_init function is used by the samsung i2s driver,
which can be a loadable module, so we have to export this function.

With multiplatform kernels, we cannot use hardwired IRQ
numbers in device drivers. This changes the idma driver
to use a proper resource, like all other drivers do.

CONFIG_HOTPLUG is going away as an option. As result the __dev*
markings will be going away.
Remove use of __devinit, __devexit_p, __devinitdata, __devinitconst,
and __devexit.

This is a follow up on 53dea36c70 which fixes the other affected
pcm engines.
Description from 53dea36c70:
Don't rely on the codec's channels_min information to decide wheter or
not allocate a substream's DMA buffer. Rather check if the substream
itself was allocated previously.
Without this patch I was seeing null-pointer dereferenc in atmel-pcm.

We always store the register address as __iomem but pass it around as a
plain void * which upsets sparse.

Lots of sound drivers were getting module.h via the implicit presence
of it in <linux/device.h> but we are going to clean that up. So
fix up those users now.

I2S in Exynos4 and S5PC110(S5PV210) has a internal dma.
It can be used low power audio mode and 2nd channel transfer.
This patch can support idma.
