MLK-9785-2 usb: chipidea: add AHB configuration interface
The AHBBRST at SBUSCFG and RX/TX burst size at BURSTSIZE are implementation
dependent, each platform may have different values, and some values may not be
optimized.
The glue layer can override ahb burst configuration value by setting flag
CI_HDRC_OVERRIDE_AHB_BURST and ahbburst_config.
The glue layer can override RX/TX burst size by setting flag
CI_HDRC_OVERRIDE_BURST_LENGTH and burst_length.
