ppc: Increase deglitch time on SN5S330
The default deglitch time is short enough to trip the current limit with
some commercially available USB-C -> HDMI adapters. Increase the
deglitch timeout to improve compatibility with those adapters.
BUG=b:113777138, b:113365815
BRANCH=none
TEST=Insert 7 different USB-C to HDMI adapters, including both
single-function and multifunction devices, and observe that a Careena
clamshell will extend the screen to include the attached monitor on both
USB-C ports 0 and 1. Brands tested include SIIG, StarTech, Amazon
basics, iogear, Apple, and an unlabeled device.
