This patch adds the 'device_config' and 'device_prep_slave_sg' interfaces
for users to configure DMA, as well as adding one 'struct sprd_dma_config'
structure to save Spreadtrum DMA configuration for each DMA channel.

This is one preparation patch, we can use default DMA configuration to
implement the device_prep_dma_memcpy() interface instead of issuing
sprd_dma_config().
We will implement one new sprd_dma_config() function with introducing
device_prep_slave_sg() interface in following patch. So we can remove
the obsolete sprd_dma_config() firstly.

We recently cleaned this code up but we need to update the error
handling as well. The devm_ioremap_resource() returns error pointers on
error, never NULL.

Instead of checking the return value of platform_get_resource(), we can

platform_get_resource() may fail and return NULL, so we should
better check it's return value to avoid a NULL pointer dereference
a bit later in the code.

Do DMAFLUSHP _before_ the first DMAWFP to ensure controller
and peripheral are in agreement about dma request state before first
transfer. Add support for burst transfers to/from peripherals. In the new
scheme, the controller does as many burst transfers as it can then
transfers the remaining dregs with either single transfers for
peripherals, or with a reduced size burst for memory-to-memory transfers.

Request IRQ with IRQF_SHARED flag to enable setups with multiple

Since commit 9b5ba0df4ea4f940 ("ARM: shmobile: Introduce ARCH_RENESAS")
is CONFIG_ARCH_RENESAS a more appropriate platform check than the legacy
CONFIG_ARCH_SHMOBILE, hence use the former.
Renesas SuperH SH-Mobile SoCs are still covered by the CONFIG_CPU_SH4
check, just like before support for Renesas ARM SoCs was added.
Instead of blindly changing all the #ifdefs, switch the main code block
in sh_dmae_probe() to IS_ENABLED(), as this allows to remove all the
remaining #ifdefs.
This will allow to drop ARCH_SHMOBILE on ARM in the near future.

"This is a set of minor (and safe changes) that didn't make the initial
pull request plus some bug fixes.
The status handling code is actually a running regression from the
previous merge window which had an incomplete fix (now reverted) and
most of the remaining bug fixes are for problems older than the
current merge window"
[ Side note: this merge also takes the base kernel git repository to 6+
million objects for the first time. Technically we hit it a couple of
merges ago already if you count all the tag objects, but now it
reaches 6M+ objects reachable from HEAD.
I was joking around that that's when I should switch to 5.0, because
3.0 happened at the 2M mark, and 4.0 happened at 4M objects. But
probably not, even if numerology is about as good a reason as any.
