The ldp board was left behind when other boards got updated. The ldp info was copied from the beagleboard board file and s/beagle/ldp/g

Don't set up VSIM to power DAT4..DAT7 on boards,
like LDP, which only use DAT0..DAT3.
(That is, if this patch were correct, then it's
a bug that mmc[0].wires == 4 instead of 8...)
