xtensa: 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 xtensa/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.c file.
