Don't use writeb() in uncompress.h, to avoid the following build errors
when the "Add barriers to the I/O accessors" series is applied. Use
__raw_writeb() instead.
arch/arm/boot/compressed/misc.o: In function `putc':
arch/arm/mach-ux500/include/mach/uncompress.h:41:
undefined reference to `outer_cache'
