[ECOS] PCI spec Trhfa parameter

I notice that the PCI 2.3 spec requires a 2^25 clock
delay between deasserting reset on the bus and the first
configuration access (about 1 sec at 33 MHz clock).  I
believe this is intended to allow devices like FPGAs
and cards with an embedded CPU to set themselves up.

It looks like none of the platform hals (of the ones I
looked at) take this parameter into account when setting
up the bus.
