[PATCH 2/2] drm/panic: Fix expected string for QR_CODE in drm_panic_type_map

[Nathan Chancellor <nathan@kernel.org>]

The help text of CONFIG_DRM_PANIC_SCREEN_QR_CODE documents the expected
value to CONFIG_DRM_PANIC_SCREEN as "qr_code" but drm_panic_type_map
checks for "qr". Adjust drm_panic_type_map and the module description to
match so that existing configurations do not stop working.

Fixes: e85e9ccf3f84 ("drm/panic: Report invalid or unsupported panic modes")
