usb: gadget: bdc: 64-bit pointer capability check
commit c8e4e5bdb62a5ac6f860ebcaaf7b467b62f453f1 upstream.
Corrected the register to check the 64-bit pointer
capability state. 64-bit pointer implementation capability
was checking in wrong register, which causes the BDC
enumeration failure in 64-bit memory address.
Fixes: efed421a94e6 ("usb: gadget: Add UDC driver for
Broadcom USB3.0 device controller IP BDC")
