[PATCH] Allow selecting mv643xx_eth on Pegasos again

[Gabriel Paubert <paubert@iram.es>]

Since PPC_MUTIPLATFORM was removed, it was impossible to select the
driver for mv643xx_eth on the Pegasos. Fix by allowing to select
the driver on CHRP platforms; Pegasos is a CHRP platform and the driver
will not work wihtout arch/powerpc/platforms/chrp/pegasos_eth.

The patch also removes all references to MV64360 config option which 
no more exists.
