[Patch] Fix for build break for alpha

I noticed the build is break in the alpha due to 1.21 reversion of rman.h. In my config, I manually added the #define __RMAN_RESOURCE_VISIBLE into the following files:
src/sys/alpha/alpha/sgmap.c
src/sys/alpha/pci/cia.c
src/sys/alpha/isa/isa.c
src/sys/alpha/mcbus/mcpcia.c
src/sys/alpha/tlsb/dwlpx.c
src/sys/alpha/pci/tsunami_pci.c
to build the kernel. 

Thanks,

Jun
