Currently we are using hardcoded 7 for io and fast wake lines.

According to Bspec io and fast wake times are both 42us for
DISPLAY_VER >= 12 and 50us and 32us for older platforms.

Calculate line counts for these and configure them into PSR2_CTL
accordingly

Use 45 us for the fast wake calculation as 42 seems to be too
tight based on testing.

Bspec: 49274, 4289
