usb: xhci: remove deprecated TODO comment
The Device Context Base Address Array (DCBAA) contains pointers to device
contexts. These fields are 64-bit registers, capable of holding 64-bit
addresses.
When struct 'xhci_device_context_array' was introduced in commit [1],
the entries were represented as pairs of 'u32', requiring a custom helper
function to set 64-bit addresses. This was later made redundant by
commit [2], which changed the representation to a single 'u64', allowing
direct assignment.
The associated TODO comment referencing the old 32-bit representation is
no longer relevant and is removed.
