Marek Behún 236f2ec432 treewide: Convert macro and uses of __section(foo) to __section("foo")
This commit does the same thing as Linux commit 33def8498fdd.

Use a more generic form for __section that requires quotes to avoid
complications with clang and gcc differences.

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.
