Subject: [PATCH] kernel: Assembly: need add prefix for h8300 architecture.

Need add related prefix for h8300, or can not pass compiling by the
latest linker.

The related error (allmodconfig for h8300):

  /usr/local/bin/h8300-gchen-elf-ld: h8300 architecture of input file `usr/initramfs_data.o' is incompatible with h8300h output
  /usr/local/bin/h8300-gchen-elf-ld: h8300 architecture of input file `kernel/modsign_certificate.o' is incompatible with h8300h output

The cross-compiler's information:

  [root@...p122 linux-next]# /usr/local/bin/h8300-gchen-elf-ld -v
  GNU ld (GNU Binutils) 2.22
  [root@...p122 linux-next]# /usr/local/bin/h8300-gchen-elf-as -v
  GNU assembler version 2.22 (h8300-gchen-elf) using BFD version (GNU Binutils) 2.22
  
  [root@...p122 linux-next]# /usr/local/bin/h8300-gchen-elf-gcc -v
