usb: gadget: bdc: 64-bit pointer capability check

Browse Source 
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: efed421a94 ("usb: gadget: Add UDC driver for
Broadcom USB3.0 device controller IP BDC")
