[PATCH] drm/tegra: replace idr_init() by idr_init_base()

[Deepak R Varma]

idr_init() uses base 0 which is an invalid identifier for this driver.
The new function idr_init_base allows IDR to set the ID lookup from
base 1. This avoids all lookups that otherwise starts from 0 since
0 is always unused.
