[PATCH v2 2/2] media: aspeed: Fix incorrect resolution detected

[Jammy Huang]

During successive timing-change, resolution detected could be incorrect,
for example. Using remote KVM to do Centos-8.2 installation, the timing
detected could be only 1920x471 for 1920x1200.

Increase min-required-count of stable signal to fix the problem.
