Since SVEC relies on stacks, and not DMA, it is slower than the SPEC.
Thus, we need different speed and count for it.

Resolve "API update for debugfs_create_regset32() not handled properly"

Closes #26

See merge request be-cem-edl/fec/hardware-modules/fmc-tdc-1ns-5cha!9

After this:
	commit b208e2f7 ("software: kernel:
	ft-debug: Update API 'debugfs_create_regset32'")

The pointer `ft->dbg_reg` was never initialized. And when we
check it for "IS_ERR_ORNULL", we get false failure.

Thus, put conditional directive for this API update.

The '__sg_alloc_table_from_pages()' was expanded to support dynamic
allocation of SG table from pages for the drivers that can't supply all the
pages at one time, in linux-v5.9 at:

	commit 07da1223ec939982497db3caccd6215b55acc35c ("lib/scatterlist:
	Add support in dynamic allocation of SG table from pages")

Hence update the code to comply with this new API

The 'struct platform_device_id' is defined in 'linux/mod_devicetable.h';
this header was #include in 'linux/platform_device.h'. Hence, using the
latter header-file was enough. But in linux-v4.18 at:

	commit ac3167257b9fe16c9426c2087ead1c9f1b0992b1 ("headers: separate
	linux/mod_devicetable.h from linux/platform_device.h")

the former was no more included in the latter. Thus, we need to do it
explicitly.

Since this change makes no difference if this driver is compiled against
Kernel version less than v4.18, we do not need any conditional
directives.

In struct memory_ops, the function-pointer (*read) is declared as
	u32 (*)(void *)

In its use, its object is given the address of function 'ioread32' (or
'ioread32be') which used to be of the same type.

Since linux-v5.8, their protype has been changed to
	u32 (*)(const void *)
at:
commit 8f28ca6bd8211214faf717677bbffe375c2a6072 ("iomap: constify ioreadX()
iomem argument (as in generic implementation)")

Hence, update the declaration of (*read) as well.
