h8300: include: asm: add marco VM_DATA_DEFAULT_FLAGS in page.h

Need add VM_DATA_DEFAULT_FLAGS definition just like another platforms has done (e.g. xtensa), or can not pass compiling.

The related error (allmodconfig for h8300):

CC security/selinux/hooks.o
security/selinux/hooks.c: In function 'selinux_init':
security/selinux/hooks.c:5866:21: error: 'VM_DATA_DEFAULT_FLAGS' undeclared (first use in this function)

    default_noexec = !(VM_DATA_DEFAULT_FLAGS & VM_EXEC);
                       ^
