[coreboot-gerrit] Change in coreboot[master]: endian: Replace explicit byte swapping with compiler builtin

[Julius Werner (Code Review)]

Hello build bot (Jenkins), Patrick Georgi,

I'd like you to reexamine a change. Please visit

https://review.coreboot.org/c/coreboot/+/37343

to look at the new patch set (#2).

Change subject: endian: Replace explicit byte swapping with compiler builtin

endian: Replace explicit byte swapping with compiler builtin

gcc seems to have some stupid problem with deciding when to inline byte
swapping functions (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=92716).
Using the compiler builtin instead seems to solve the problem.

(This doesn't yet solve the issue for the read_be32()-family of
functions, which we should maybe just get rid of at some point?)
