include/linux/io-mapping.h: remove fallback for writecombine
The fallback was introduced in commit 80c33624e472 ("io-mapping: Fixup
for different names of writecombine") to fix the build on microblaze.
5 years later, it seems all archs now provide a pgprot_writecombine(),
so just remove the other possible fallbacks. For microblaze,
pgprot_writecombine() is available since commit 97ccedd793ac
("microblaze: Provide pgprot_device/writecombine macros for nommu").
This is build-tested on microblaze with a hack to always build
mm/io-mapping.o and without DIYing on an x86-only macro
