  sh: generate uapi header and syscall table header files (2018-12-19

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.

Maybe it is time to drop the code for it then?
