[PATCH v2 0/3] Fix GCC 12 build error

[Michael Chang]

The tested gcc version is:

 abuild@mazu:~> gcc --version
 gcc (SUSE Linux) 12.0.1 20220307 (experimental) [revision 
40c1d4a07e5798c01e4364336c9617550744861d]

Although it may not catch all build errors as there are quite many
combinations of cpu architecture and platform which grub supports. The
work is as far as I can get right now and I'd like to have them reviewed
before anyone running into similar problems.

v2:
Fix -Werror=array-bounds array subscript 0 is outside array bounds
1. Replace null with NULL in commit message
2. Add explain to do variable shuffling in commit message
3. Change macro grub_absolute_pointer definition to include/grub/types.h
4. Use grub_addr_t as pointer type in grub_absolute_pointer
5. Use asm keyword instead of __asm__
6. Mention RELOC_HIDE() macro in the comment of grub_absolute_pointer

Thanks,
Michael
