ARM: tegra: clock: Fix clock issues in suspend
The PLLP registers are now being restored by the low-level resume code,
and the CPU may be running off PLLP, so don't touch them during clock
resume.
Save plld, plls, pllu, and audio clock during suspend (originally
fixed by Mayuresh Kulkarni <mkulkarni@nvidia.com>)
The lock time for plld is 1000 us, so increase the delay after
setting the PLLs.
Add a BUG_ON to ensure the size of the suspend context area is
correct.
