MLK-12883 usb: limit USB_MAX_XFER_BLK to 256rel_imx_4.1.15_1.2.0_gaimx_v2015.04_4.1.15_1.0.0_ga
For Some USB mass storage devices, such as:
"
- Kingston DataTraveler 2.0 001D7D06CF09B04199C7B3EA
- Class: (from Interface) Mass Storage
- PacketSize: 64 Configurations: 1
- Vendor: 0x0930 Product 0x6545 Version 1.16
"
When `usb read 0x80000000 0 0x2000`, we met
"EHCI timed out on TD - token=0x80008d80".
The devices does not support scsi VPD page, we are not able
to get the maximum transfer length for READ(10)/WRITE(10).
So we limit this to 256 blocks as READ(6).
