[POWERPC] hvcbeat: Fix buffer manipulation
This fixes a potential bug at drivers/char/hvc_beat.c.
- hvc_put_term_char routine will decrement "rest" variable twice,
and forget to advance "buf" pointer by "nlen" bytes.
This bug was not hit previously because the output handler in
drivers/char/hvc_console.c splits given output into 16 bytes
at maximum.
