x86, numa: Remove configurable node size support for numa emulation

Browse Source 
Now that numa=fake=<size>[MG] is implemented, it is possible to remove
configurable node size support.  The command-line parsing was already
broken (numa=fake=*128, for example, would not work) and since fake nodes
are now interleaved over physical nodes, this support is no longer
required.

If given as a memory unit, fills all system RAM with nodes of
size interleaved over physical nodes.
numa=fake=CMDLINE
If a number, fakes CMDLINE nodes and ignores NUMA setup of the
actual machine. Otherwise, system memory is configured
depending on the sizes and coefficients listed. For example:
numa=fake=2*512,1024,4*256,*128
gives two 512M nodes, a 1024M node, four 256M nodes, and the
rest split into 128M chunks. If the last character of CMDLINE
is a *, the remaining memory is divided up equally among its
coefficient:
numa=fake=2*512,2*
gives two 512M nodes and the rest split into two nodes.
Otherwise, the remaining system RAM is allocated to an
additional node.
numa=fake=<N>
If given as an integer, fills all system RAM with N fake nodes
interleaved over physical nodes.
