Use a more generic form for __section that requires quotes to avoid

Remove the quote operator # from compiler_attributes.h __section macro.

Convert all unquoted __section(foo) uses to quoted __section("foo").
Also convert __attribute__((section("foo"))) uses to __section("foo")
even if the __attribute__ has multiple list entry forms.

Conversion done using a script:

Nick Desaulniers found a defect in the conversion of 2 boot files
for powerpc, but no other defect was found for any other arch.

Untested, but:
Reviewed-by: Nick Desaulniers <redacted>

Good job handling the trickier cases when the attribute was mixed with
others, and printing it in scripts/mod/modpost.c.

The only cases that *might* be similar to PPC are:

 arch/s390/boot/startup.c              |  2 +-
 arch/x86/boot/compressed/pgtable_64.c |  2 +-
 arch/x86/purgatory/purgatory.c        |  4 ++--

So a quick test of x86_64 and s390 would be good.

Thanks for the patch.

The script was corrected to avoid converting these 2 files.

There is no difference between the script output when run on today's -next
and Linus' tree through commit f804b3159482, so this should be reasonable to
apply now.
