usb: ehci: HBM require 64-byte aligned QH and qTD data structures
HBM block contains USB_OTG_HS_HBM_QH_MAP_PIPEn SW registers that map
BAM pipes to QHeads. However the USB_OTG_HS_HBM_QH_MAP_PIPEn registers
have only 31:6 valid bits, bits 5:0 are reserved, thus 64 bytes boundary
alignment is required.
