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.

The return type of 'debugfs_create_regset32()' was changed to 'void'
in linux-v5.6 at commit:

	value of debugfs_create_regset32()")

Variable name 'LINUX' is very ambiguous for its purpose in the makefile.
Also, this project builds as a part of COHT project which uses another
variable name 'KERNELSRC' for the same purpose. Hence, this change makes
this project uniform with others.

At the end the carrier offset value for White-Rabbit has been always
constant and it depends on the hardware:
- SVEC: 3000 ps
- SPEC:    0 ps

so, instead of complicate users life by setting this module parameter,
here I am embedding it into the platform_data for the TDC.

The ideal solution would be to ignore this value in software and to
apply it in HDL directly.

The block cannot be completly removed as it defines some registers that
are still used even when the fifos are not present.

100ns is the very minimum that the TDC can accept, give 1ns of margin
