arm/km: introduce kmsugp1 target
KMSUGP1 is from a u-boot perspective (almost) identical to KMNUSA.
The only difference is that the PCIe reset is connected to Kirkwood pin
MPP7_PEX_RST_OUTn, we use a dedicated config flag KM_PCIE_RESET_MPP7.
Such pin should theoretically be handled by the PCIe subsystem
automatically, but this turned out not to be the case.
So simply configure this PIN as a GPIO and issue a pulse manually.
