The dma-heap will allocate a scatterlist table at alloc time and store
into the heap buffer. Usually a device should attach to the dmabuf and
then map the dmabuf with the attachment, a new scatterlist table will be
created and set during dma map.
In the dma map, the sg_dma_address will be set for the first scatter of
the scatterlist table, if the device has a iommu domain, sg_dma_address
is set with the iova start address, else it will be set with a physical
address.
For a dmabuf hasn't been dma mapped, the sg_dma_address is a error value
(-1 = DMA_MAPPING_ERROR).
The partial sync hits the case that no device mapped to the dmabuf.
It's not easy to support both iommu/no iommu devices for partial sync,
this patch make the partial sync simple to implement for no iommu case.

Switch to use for_each_sgtable_sg to use orig_nents instead of nents for
the for the partial sync sgl.
struct sg_table is a common structure used for describing a memory
buffer. It consists of a scatterlist with memory pages and DMA addresses
(sgl entry), as well as the number of scatterlist entries: CPU pages
(orig_nents entry) and DMA mapped pages (nents entry).
It turned out that it was a common mistake to misuse nents and orig_nents
entries, calling the scatterlist iterating functions with a wrong number
of the entries.
To avoid such issues, lets introduce a common wrappers operating directly
on the struct sg_table objects, which take care of the proper use of
the nents and orig_nents entries.

This patch add pll frac freq around 1G for audio product,
which will do fine tune pll for async clk situation,
such as BT, UAC.
Because we have no much more PLLs, and much more devices
share the same PLL, so, we should setup around 1G to serve
all the devices.
PLLs in rv1106:
APLL: CPU
DPLL: DDR
GPLL: DEVICES
CPLL: DEVICES
GPLL: 1188MHz
CPLL: 1000MHz
* PLLs support frac mode:
GPLL
DPLL
So, the only way to use audio pll frac freq is to switch to
use GPLL. and switch the role of GPLL and CPLL.
GPLL: audio frac freq (~1G)
CPLL: 1188MHz
Tested by UAC product, so, we first address this. and, of course,
there still have chance apply this to other situation, such as IPC.
but, need more test. at this time, we just handle for UAC.
