The split into multiple structures of the "ll" register bank is impractical. It makes it hard to add ll_lfps_timers_2 which is at offset 0x794, which is outside of the existing "lfps" structure and would require us to add yet another one. Instead, move all the "ll" registers into a single usb338x_ll_regs structure, and add ll_lfps_timers_2 while at it. It will be used in a subsequent patch.
