[U-Boot] [UBOOT RFC PATCH 13/13] dwc3: core: Change the bounce buffer size to 4096

[Kishon Vijay Abraham I]

Bounce buffer is used for transferring requests which is not maxpacket
aligned. In the case of DFU the requests can be upto 4096 bytes.

While the actual fix for this should be using two chained TRBs to handle
the transfer, this can be used as a temporary fix.
