dma: rcar-audmapp: Fix for no corresponding slave ID
In case of no corresponding slave ID, the audmapp_set_slave() returns
-ENXIO same as sh_dmae_set_slave() of shdmac.c.

dmaengine: shdma: Allocate cyclic sg list dynamically
The sg list used to prepare cyclic DMA descriptors is currently
allocated statically on the stack as an array of 32 elements. This makes
the shdma_prep_dma_cyclic() function consume a lot of stack space, as
reported by the compiler:
drivers/dma/sh/shdma-base.c: In function ‘shdma_prep_dma_cyclic’:
drivers/dma/sh/shdma-base.c:715:1: warning: the frame size of 1056 bytes
is larger than 1024 bytes [-Wframe-larger-than=]
Given the limited Linux kernel stack size, this could lead to stack
overflows. Fix the problem by allocating the sg list dynamically.

dmaengine: shdma: Make channel filter ignore unrelated devices
The shdma_chan_filter() function relies on the DMA channel being
embedded in an shdma_chan structure. If this assumption isn't true, for
instance when the system contains DMA channels supported by an unrelated
driver, the function will crash.
Avoid this by returning false directly when the channel belongs to an
unrelated device.

rcar-hpbdma: add parameter to set_slave() method
Commit 4981c4dc194efb18f0e9a02f1b43e926f2f0d2bb (DMA: shdma: switch DT mode to
use configuration data from a match table) added a new parameter to set_slave()
method but unfortunately got merged later than commit c4f6c41ba790bbbfcebb4c47a
(dma: add driver for R-Car HPB-DMAC), so that the HPB-DMAC driver retained the
old prototype which caused this warning:
drivers/dma/sh/rcar-hpbdma.c:485: warning: initialization from incompatible
pointer type
The newly added parameter is used to override DMA slave address from 'struct
hpb_dmae_slave_config', so we have to add the 'slave_addr' field to 'struct
hpb_dmae_chan', conditionally assign it in set_slave() method, and return in
slave_addr() method.

dma: sh: use an integer slave ID to improve API compatibility
Initially struct shdma_slave has been introduced with the only member - an
unsigned slave ID - to describe common properties of DMA slaves in an
extensible way. However, experience shows, that a slave ID is indeed the
only parameter, needed to identify DMA slaves. This is also, what is used
by the core dmaengine API in struct dma_slave_config. We switch to using
the slave_id directly, instead of passing a pointer to struct shdma_slave
to improve compatibility with the core. We also make the slave_id signed
for easier error checking.

dmaengine: shdma: (cosmetic) simplify a static function
dmae_find_slave() needs only the slave_id field from the slave object, no
need to pass the pointer to the object, pass the slave_id directly.

dmaengine: add an shdma-base library
This patch extracts code from shdma.c, that does not directly deal with
hardware implementation details and can be re-used with diverse DMA
controller variants, found on SH-based SoCs.
