Save the pointer of efi_ctx in mi_drivers_addr field of
multiboot structure and pass to hypervisor, not by
saving in register RDX(the third default parameter in
64bit call function).
With this method, we can be compatible with the original
32bit boot parameters passing method and no need to
large the array size of boot_regs in hypervisor.

With current code, the acrn.efi is inserted between
cl bootloader.efi and bzImage.efi that destroyed the chain
relationship of cl bootloader and cl bzImage.efi.
And the following is current boot flow:
UEFI -> cl bootloader.efi -> acrn.efi -> bzImage.efi
The purpose of this patch is resume above chain relationship,
and make uefi vm return to efi stub context once launched,
then continue to call the UEFI API(LoadImage/StartImage) to launch
cl bootloader or other bootloaders. So the boot flow will
change to be as below:
UEFI -> acrn.efi -> cl bootloader.efi -> bzImage.efi
After applying this patch, the code related to loading
bzImage.efi and getting pe_entry is unnecessary due to
the bzImage.efi will not be launched by acrn.efi directly,
so it is removed.

With current code, memcpy rsdp to 0x500 maybe overwrite uefi
code/data region.
So remove the legacy BIOS deliver method of RSDP, which need copy
the RSDP to EBDA space which is addressed by the 16bit pointer
at 0x40E or upper memory BIOS space 0xe0000-0xfffff. And just
deliver the pointer of RSDP, which is already saved in UEFI system
table, to hypervisor.
Create a function named efi_init() to separate efi initialize code.

As mentioned in https://github.com/projectacrn/acrn-documentation/pull/38
on some operating systems, the ``gnu-efi`` package installs the
linker under a ``gnuefi`` folder in ``${LIBDIR}``. This is the
case in Fedora for example. Check if the gnuefi folder is there
and use it if it is in the path to the linker. This PR fixes the
Makefile rather than documenting how to edit it yourself.

The EFI configuration example file is not installed.
This patch adds a rule to install the configuration example file
at /usr/share/acrn

Currently the acrn EFI hypervisor file is installing directly to
/usr/share. This patch adds a "acrn" directory to store in
/usr/share/acrn
