[ Upstream commit 510e7261a7bcd6232e90f0b6b9f93303bdd29f8a ]

Update the device ID for Dell XPS 13 7390 2-in-1 in the quirk
`QUIRK_EDP_LIMIT_RATE_HBR2` entry. The previous ID (0x8a12) was
incorrect; the correct ID is 0x8a52.

Closes: https://gitlab.freedesktop.org/drm/i915/kernel/-/issues/5969
Fixes: 21c586d9233a ("drm/i915/dp: Add device specific quirk to limit eDP rate to HBR2")
