[RFC PATCH 03/15] dm: Add a way to write the internal seq_ member

[Simon Glass]

Add a dev_int_set_seq() inline in device-internal.h to wrap writes to
dev->seq_ from outside the driver-model core. This is the write side of
dev_seq() and should be used only when absolutely necessary.

Use it in pci-uclass.c which is the only external caller that sets
seq_ directly.
