Revert "Mark xe driver as BROKEN if kernel page size is not 4kB"

JIRA: https://issues.redhat.com/browse/RHEL-113577
Upstream Status: RHEL only

This reverts commit 022906a.

This commit was backported automatically as part of the DRM backport.

Upstream commit ba89f9c ("arch: consolidate existing
CONFIG_PAGE_SIZE_*KB definitions") is not present in this tree,
disabling the XE driver as a side effect.

In RHEL 9, XE is only enabled for x86_64 and, as described in the
reverted patch, this architecture is fine, so it is safe to revert
the change:

> This driver, for the time being, assumes that the kernel page size is
> 4kB, so it fails on loong64 and aarch64 with 16kB pages, and ppc64el
> with 64kB pages.

NOTE: This commit does not compile due to missing RHEL-specific fix-ups,

If git bisect selected this commit, run "git bisect skip" and try again.
Repeat this until it selects a commit which compiles.
