Drop support for Renesas H8/300 (h8300) architecture
H8/300 has been dead for several years, and the kernel for it has not compiled for ages. Drop support for it. Cc: Yoshinori Sato <ysato@users.sourceforge.jp> Acked-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Guenter Roeck <linux@roeck-us.net>

- bits 15..9 (SHM_ID) the id of the shared memory segment
- bits 30..16 (SHM_IDX) the index of the page within the shared memory segment
- (actually only bits 25..16 get used since SHMMAX is so low)
- bit 31 (SHM_READ_ONLY) flag whether the page belongs to a read-only attach
