device/xhci: Add functions to work with resource pointers

The XHCI device functions currently use functions that require a
access to the device tree. Create variant of these functions that can
operate with a resource* as an argument and refactor the existing
device*-based functions to operate by calling the resource*-based
variants. This is useful for stages like SMM that may not have access to
the device tree.

BRANCH=guybrush
BUG=b:186792595
TEST=Ran on skyrim device, verified that XHCI ACPI tables are still
generated correctly.
