drm/amdgpu/display: switch udelay to msleep
We may need to sleep for up to 80ms
(8ms per each of up to 10 loop iterations):
/* First DPCD read after VDD ON can fail if the particular board
* does not have HPD pin wired correctly. So if DPCD read fails,
* which it should never happen, retry a few times. Target worst
* case scenario of 80 ms.
*/
Switch udelay to msleep to avoid limits on arm.
