asm-generic: syscall table script for arch/sh

I worked with Firoz Khan to change all architectures to have their system
call tables (syscall.S and asm/unistd.h) generated by a script from a more
readable input file the same way that we already had on x86, s390 and arm.

I offered to take those conversions through the asm-generic tree that
did not get picked up by the architecture maintainers, and fortunately
all but one have now been accepted into arch maintainer trees, so this
branch only contains the conversion for arch/sh/, with permission from
Rich.

The conversion does not include the old 64-bit sh5 architecture, which
has never shipped and not even compiled in a long time. The table
in include/uapi/asm/unistd.h is also not included here, as Firoz is
still working on that one, it will have to wait for the next following
merge window, hopefully together with the addition of the 64-bit
time_t system calls for the y2038 work that led to the system call
table rework.

sh: generate uapi header and syscall table header files

System call table generation script must be run to gener-
ate unistd_32.h and syscall_table.h files. This patch will
have changes which will invokes the script.

This patch will generate unistd_32.h and syscall_table.h
files by the syscall table generation script invoked by
sh/Makefile and the generated files against the removed
files must be identical.

The generated uapi header file will be included in uapi/-
asm/unistd.h and generated system call table header file
will be included by kernel/syscall_32.S file.
