drm/bridge: ti-sn65dsi83: Fix delay after reset deassert to match spec

Browse Source 
[ Upstream commit 4b03d5e0d3e86ee492d54254927d020dc0fe8acf ]

The datasheet specifies a delay of 10 milliseconds, but the current
driver only waits for 1 ms. Fix this to make sure the initialization
sequence meets the spec.
