[POWERPC] fsl_lbc: implement few UPM routines

Freescale UPM can be used to adjust localbus timings or to generate
orbitrary, pre-programmed "patterns" on the external Localbus signals.
This patch implements few routines so drivers could work with UPMs in
safe and generic manner.

So far there is just one user of these routines: Freescale UPM NAND
driver.
