iommu/io-pgtable-arm: Rationalise VTCR handling
Commit 05a648cd2dd7 ("iommu/io-pgtable-arm: Rationalise TCR handling") reworked the way in which the TCR register value is returned from the io-pgtable code when targetting the Arm long-descriptor format, in preparation for allowing page-tables to target TTBR1. As it turns out, the new interface is a lot nicer to use, so do the same conversion for the VTCR register even though there is only a single base register for stage-2 translation.
