[PATCH 0/1][B][E][F][OEM-OSP1-B] Sometimes can't adjust brightness on Dell AIO

[AceLan Kao]

BugLink: https://bugs.launchpad.net/bugs/1862885

[Impact]
We already added retry on the backlight driver, but the scalar have to
take some time to activate panel during booting up, and 2 seconds seem
doesn't enough. So, it sometimes fails to get the response from scalar.

[Fix]
Enlarge the retry time from 2 seconds to 5 seconds.
We didn't observe the response time longer than 3 seconds, but to be
more confident, enlarge the value to 5 seconds.

[Test]
Verified on new Dell AIO platform.

[Regression Potential]
Low, increase the retry times doesn't hurt anything.
