Add emulation for /proc/cpuinfo for the alpha architecture.
alpha output example:
(alpha-chroot)root@p100:/# cat /proc/cpuinfo

system revision : 0
system serial number : AY00000000
cycle frequency [Hz] : 250000000
timer frequency [Hz] : 250.00
page size [bytes] : 8192
phys. address bits : 44
max. addr. space # : 255
BogoMIPS : 2500.00
platform string : AlphaServer QEMU virtual machine
