Make loader/i386/linux.c usable on i386-pc again.

        * kern/i386/pc/init.c (grub_machine_init): Disable addition of low
        memory to heap.
        * loader/i386/linux.c [GRUB_MACHINE_PCBIOS] (allocate_pages): Remove
        `#error' stanza.

9290711060 * loader/i386/linux.c (grub_rescue_cmd_initrd): Implement a few needed 
constraints to initrd allocation (based on code from
        loader/i386/pc/linux.c).  Without them, initrd was allocated too high
        for Linux to find it.

2f2a344257 Add #error instance with comment to explain why this 
loader isn't currently usable on PC/BIOS.

* include/grub/i386/coreboot/memory.h (GRUB_MEMORY_MACHINE_LOWER_SIZE):
        Redefine to match with GRUB_MEMORY_MACHINE_UPPER_START (0x100000).  We
        don't want to mess with lower memory, because it is used in the Linux
        loader.

        * loader/i386/linux.c (allocate_pages): Allocate `real_mode_mem' in
        an appropiate place in lower memory, between 0x10000 and 0x90000,
        like loader/i386/efi/linux.c does.  Linux often panics if real_mode_mem
        is in our heap (probably as a result of it being corrupted during
        decompression).

* loader/i386/linux.c: New file.  Implements generic 32-bit Linux
        loader.
        * conf/i386-coreboot.rmk (_linux_mod_SOURCES): Replace
        `loader/i386/pc/linux.c' with `loader/i386/linux.c'.
