Added DMA driver changes for Stoney platform.
Below are the key differences between Stoney and CZ
In Stoney, Memory Gating is disabled.SRAM Banks won't
be turned off.No Of SRAM Banks reduced to 6.
DAGB Garlic Interface used and 16 bit resolution is supported.
SRAM bank 1 & SRAM bank 2 will be used for playback scenario.
SRAM Bank 3 & SRAM Bank 4 will be used for Capture scenario.

For Stoney platform, Memory gating is disabled.i.e SRAM Banks
won't be turned off. By Default, SRAM Bank state set to ON.
Added condition checks to skip SRAM Bank state set logic for
Stoney platform.

I kept the TSL2563_INT_DISBLED in /drivers/iio/light/tsl2563.c
untouched. The macro is not referenced at all, but this commit is
touching only comment blocks just in case.

In acp_dma_hw_params(), 'dma_buffer' is initialized, but not used. So
remove it.

Check for snd_pcm_ops structures that are only stored in the ops field of a
snd_soc_platform_driver structure or passed as the third argument to
snd_pcm_set_ops. The corresponding field or parameter is declared const,
so snd_pcm_ops structures that have this property can be declared as const
also.
The semantic patch that makes this change is as follows:

ACP SRAM banks gets turned on when ACP is powered on.
Not all banks are used for playback/capture. So, power on
required banks during audio device open and power off during
audio device close.

genpd will power off/on ACP to manage runtime ACP PM. ACP runtime PM
hooks are added to get it deinitialized and initialized respectively,
after it is powered off/on.
When system goes to suspend when audio usecase is active, ACP will
be powered off through genpd. When it resumes, ACP needs to be
initialized and reconfigured.

ACP IP has internal DMA controller with multiple channels which
can be programmed in cyclic/non cyclic manner. ACP can generate
interrupt upon completion of DMA transfer, if required.
The PCM driver provides the platform DMA component to ALSA core.
