    include/grub/i386/pc/int.h: Move GRUB_MACHINE_PCBIOS ifdef

    Modern compilers are becoming more strict and starting to warn when
    certain attributes are ignored. The regparam attribute is such an
    attribute.

    Moreover, the function

      void EXPORT_FUNC (grub_bios_interrupt) (grub_uint8_t intno, struct grub_bios_int_registers *regs) __attribute__ ((regparm(3)));

    is only defined with the i386-pc target.

    Update include/grub/i386/pc/int.h so grub_bios_interrupt() is only
    declared when GRUB_MACHINE_PCBIOS is defined. This addresses the issue
    of declaring a function that is not defined for non-i386-pc targets and
    prevents the "attribute ignored" diagnostic message.
