Now that the GRUB has a grub_efi_get_secureboot() function to check the
UEFI Secure Boot status, use it to report that to the Linux kernel.

This header uses types defined in <grub/types.h> but does not include it,
which leads to compile errors like the following:
In file included from ../include/grub/cpu/linux.h:19,
from kern/efi/sb.c:21:
../include/grub/i386/linux.h:80:3: error: unknown type name ‘grub_uint64_t’

Previously the setup_header length was just assumed to be the size of the
linux_kernel_params struct. The linux x86 32-bit boot protocol says that the
end of the linux_i386_kernel_header is at 0x202 + the byte value at 0x201 in
the linux_i386_kernel_header. So, calculate the size of the header using the
end of the linux_i386_kernel_header, rather than assume it is the size of the
linux_kernel_params struct.
Additionally, add some required members to the linux_kernel_params
struct and align the content of linux_i386_kernel_header struct with
it. New members naming was taken directly from Linux kernel source.
linux_kernel_params and linux_i386_kernel_header structs require more
cleanup. However, this is not urgent, so, let's do this after release.
Just in case...

Xen PVH guests will have the RSDP at an arbitrary address. Support that

The EFI Graphics Output Protocol can return a 64-bit
linear frame buffer address in some firmware/BIOS
implementations. We currently only store the lower
32-bits in the lfb_base. This will eventually be
passed to Linux kernel and the efifb driver will
incorrectly interpret the framebuffer address as
32-bit address.
The Linux kernel has already added support to handle
64-bit linear framebuffer address in the efifb driver
since quite some time now.
This patch adds the support for 64-bit linear frame
buffer address in GRUB to address the above mentioned
scenario.
