Like the old __section macro, the __alias macro uses macro #
stringification to create quotes around the symbol name used in the
__attribute__.

This can cause differences between gcc and clang when the stringification
itself contains a quote character.  So avoid these differences by always
using quotes to define the aliased symbol.

Remove the stringification and add quotes and when necessary a
stringification when existing uses have a ## concatenation.

Unlike the __section macro conversion in commit 33def849 ("treewide:
Convert macro and uses of __section(foo) to __section("foo")") this one
was done by hand.

No other use of __alias exists in the kernel.

This patch does _not_ convert any uses of __attribute__((alias("<foo>")))
so it should not cause any compilation issues.
