[PATCH] ARM: mach-davinci: Select PHYLIB for ARCH_DAVINCI_DM644x

We call phy_register_fixup_for_uid in davinci_evm_init, thus we need 
select PHYLIB to fix below build error: (with "make davinci_all_defconfig")

  LD      .tmp_vmlinux1

This shouldn't happen with davinci_all_defconfig as it
selects PHYLIB (this doesn't undermine the need for a fix).

Selecting PHYLIB for the SoC isn't right because
only the EVM is affected by this issue.

Also, instead of selecting PHYLIB, a better fix
would be to define the fixup function within
#ifdef PHYLIB and have an empty fixup registration
function in case PHYLIB is not defined (which
should happen only when EMAC driver is not configured
in which case a fixup is not required anyway).

Thanks,
Sekhar

I remember that I got the build error with davinci_all_defconfig, but
the build seems ok now with linux-next ( next-20110831 ).
