MLK-12883 usb: limit USB_MAX_XFER_BLK to 256

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).

MA-8202 [Android_MX6DL_ARD] Fastboot: Failed to boot system if update…

… android_root.img based on NAND boot. 100%

For sparse system.img, USB can trasfer system.img through spliting image into two sparse images.
For android_root.img, the second part will overwrite the first one.
It is a workaround to enlarge CONFIG_USB_FASTBOOT_BUF_SIZE to hold system image whose size is more than 400M.

MLK-12576 imx: imx6ul: disable POR_B internal pull up

From TO1.1, SNVS adds internal pull up control for POR_B,
the register filed is GPBIT[1:0], after system boot up,
it can be set to 2b'01 to disable internal pull up.
It can save about 30uA power in SNVS mode.

2. Change 2 values to compatible with our DDR aid script,
   these two registers doesn’t have any effect on current system
   tRPA = 0;
   //this bit only used in DDR2 mode
   tAOFPD/tAONPD=0x4;
   //These register only works when MDPDC. SLOW_PD = 1 which is 0 in script

Test results:
One mx6qp-sdb and one mx6qp-ard board and one mx6qp-ard board passed
