drm/tegra: replace idr_init() by idr_init_base()
[ Upstream commit 41f71629b4c432f8dd47d70ace813be5f79d4d75 ]
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.
