[PATCH 1/4] semihosting: Move ARM semihosting code to shared directories

[Keith Packard]

This commit renames two files which provide ARM semihosting support so
that they can be shared by other architectures:

 1. target/arm/arm-semi.c     -> hw/semihosting/common-semi.c
 2. linux-user/arm/semihost.c -> linux-user/semihost.c

The build system was modified to reflect this change, but the contents
of the two files are unchanged.
