Revert previous. PR/48431 claims ALPHA_PHYS_TO_K0SEG() is necessary.

Browse Source 
Actually CHIP_MEM_SYS_START(v) seems a physical address per *_mem_map()
function, but I don't think mmap() function should return K0SEG address
(it should return PA cookie IIUC) so I guess there is something wrong
in Titan's bus space functions.  I'll investigate them later.
