ipq807x: Add delay for Get descriptor

REQUEST SUMMARY
Setup Data 8006000200000900 Direction Device-to-host
Type Standard Recipient Device
bRequest GET_DESCRIPTOR wValue CONFIGURATION, Index 0
wIndex 0x0000 wLength 0x0009

DECODING INFORMATION

  Field Length(bits) Offset(bits) Decoded HexValue Description
  bRequest     8     8     GET_DESCRIPTOR     0x06     bRequest HexVal: 0x06
  wValue     16     16     CONFIGURATION type, Index 0     0x0200     Type of Descriptor
  wIndex     16     32     0x0000     0x0000     index info

DEVICE_QUALIFIER
  Descriptor(128 bytes) Field  Length(bits) Offset(bits)   Decoded HexValue Description
  bLength     8     0      0x80      0x80     Descriptor size is 128 bytes
  bDescriptorType     8     8      0x06      0x06     DEVICE_QUALIFIER Descriptor Type
  bcdUSB     16     16      0x0200      0x0200     USB Specification version 2.00
  bDeviceClass     8     32      0x00      0x00     Each interface specifies its own class information
  bDeviceSubClass     8     40      0x00      0x00     Each interface specifies its own Subclass information
  bDeviceProtocol     8     48      0x09      0x09     Protocol code = 9
  bMaxPacketSize0     8     56      0x00      0x00     The Maximum packet size 0 for endpoint zero is invalid! (Only 8,16,32,or 64 are valid)
  bNumConfigurations     8     64      0x09      0x09     The device has 9 possible other-speed configurations

The Transcend device fails for get configuration descriptor length.
Adding a delay fixes the issue.
