This patch removes the Sequoia "bootstrap" command and replaces it with the now common command "chip_config".
Please note that the patches with the dynamic PCI sync clock configuration have to be applied, before this one should go in. This is because Sequoia has 2 different bootstrap EEPROMs, and the old bootstrap command configured different values depending on the detected PCI async clock (33 vs. 66MHz). With the PCI sync clock patches, this is not necessary anymore. The PCI sync clock will be configured correctly on-the-fly now.
