An old comment in get_phys_addr_lpae() claims that the code does not support the different format TCR for VTCR_EL2. This used to be true but it is not true now (in particular the aa64_va_parameters() and aa32_va_parameters() functions correctly handle the different register format by checking whether the mmu_idx is Stage2). Remove the out of date parts of the comment.
