Subject: powerpc/ptdump: rename "struct pgtable_level" to "struct ptdump_pglevel"
Date: Mon, 11 Aug 2025 13:26:26 +0200

We want to make use of "pgtable_level" for an enum in core-mm. Other
architectures seem to call "struct pgtable_level" either:
* "struct pg_level" when not exposed in a header (riscv, arm)
* "struct ptdump_pg_level" when expose in a header (arm64)

So let's follow what arm64 does.
