[PATCH RESEND 09/10] drm/via: use idr_init_base() to initialize dev_priv->object_idr

[Danilo Krummrich]

idr_init_base(), implemented by commit 6ce711f27500 ("idr: Make 1-based
IDRs more efficient"), let us set an arbitrary base other than
idr_init(), which uses base 0.

Since, for this IDR, no ID < 1 is ever requested/allocated, using
idr_init_base(&idr, 1) avoids unnecessary tree walks.
