Those properties are no longer parsed by the driver which is being passed
those information by the core now. Let's deprecate them.

- fsl,upm-cmd-offset : UPM pattern offset for the command latch.
Optional properties:
-- fsl,upm-wait-flags : add chip-dependent short delays after running the
- UPM pattern (0x1), after writing a data byte (0x2) or after
- writing out a buffer (0x4).
- fsl,upm-addr-line-cs-offsets : address offsets for multi-chip support.
The corresponding address lines are used to select the chip.
- gpios : may specify optional GPIOs connected to the Ready-Not-Busy pins
(R/B#). For multi-chip devices, "n" GPIO definitions are required
according to the number of chips.
