[ Upstream commit 8f1880cbe8d0d49ebb7e9ae409b3b96676e5aa97 ]
With the implementation of the system reset controller we lost a setting that is currently applied by the bootloader and which configures the IMP port for 2Gb/sec, the default is 1Gb/sec. This is needed given the number of ports and applications we expect to run so bring back that setting.
