Log Message:
-----------
MdeModulePkg/UsbBusPei: Use dynamic buffer for USB configuration data
USB devices whose configuration descriptor TotalLength exceeds 1024
bytes (e.g. IR cameras with large descriptor tables) previously hit
an EFI_DEVICE_ERROR hard-limit and failed to enumerate in PEI.
Replace the fixed array with a UINT8 * pointer and dynamically
allocate the exact amount of memory required via
PeiServicesAllocatePool() after the TotalLength is learned from the
initial 4-byte descriptor probe.
