wctdm24xxp, wcte12xp: Allow VPMADT032 commands more time to complete.

Browse Source 
Since "wctdm24xxp: Probe for and configure modules in parallel." the
check for the VPMADT032 module was moved closer to after when the
interface was initialized. The 200ms timeout did not provide enough
time for the system to settle out after initial start. The result
was that sometimes after a cold boot the driver would fail to detect
any VPMADT032 modules.

This fixes a race condition that is not in any released branches.
