Subject: [PATCH] iommu/amd: remove h from printk format specifier

From: Tom Rix <trix@...hat.com>

See Documentation/core-api/printk-formats.rst.

commit cbacb5ab0aa0 ("docs: printk-formats: Stop encouraging use of unnecessary %h[xudi] and %hh[xudi]")

Standard integer promotion is already done and %hx and %hhx is useless
so do not encourage the use of %hh[xudi] or %h[xudi].
