Nicolin Chen 82fa58e81d iommu/tegra-smmu: Do not use PAGE_SHIFT and PAGE_MASK
PAGE_SHIFT and PAGE_MASK are defined corresponding to the page size
for CPU virtual addresses, which means PAGE_SHIFT could be a number
other than 12, but tegra-smmu maintains fixed 4KB IOVA pages and has
fixed [21:12] bit range for PTE entries.

So this patch replaces all PAGE_SHIFT/PAGE_MASK references with the
macros defined with SMMU_PTE_SHIFT.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
