Property "snps,incr-burst-type-adjustment = <x>, <y>..." for USB3.0
DWC3.When only one value means INCRx mode with fix burst type.
When more than one value, means undefined length burst mode, USB
controller can use the length less than or equal to the largest
enabled burst length.
While enabling undefined length INCR burst type and INCR16 burst type,
get better write performance on NXP Layerscape platforms: around 3%
improvement (from 364MB/s to 375MB/s).
