tegra11: nvavp: clock: increase sclk boost frequency
25x16 panel requires higher slck frequency than 19x12. So increase the sclk
from 40MHz to 80MHz. This reuses the mechanism in existing avp driver. Previous
code is to boost sclk when display is turned on to prevent glitch audio. It's
general enough so not necessary to introduce another duplicate framework just
to boost sclk for similar performance issues.
And, this is only for runtime boosting. When system is idle with display off,
previous commit 9f82f47 (ARM: tegra11: clock: decrease sclk min limit) has
ensured that the sclk is at the lowest possible speed to save power.
