But at the same time, if device receives HPD_IRQ attention event, DP driver is trying to access unclocked registers. Handle HPD_IRQ attention event only if DP is fully powered ON.

But during device boot up if continuous splash is enabled then we don't need to toggle the FIFO resync bit, since DSI PLL will be already enabled by UEFI. So avoid toggling FIFO resync if continuous splash is enabled. Change-Id: I94f3e0e48799ded8e546f3889b3df0a8af577451 Signed-off-by: Sandeep Panda <spanda@codeaurora.org>

Subsequently the buffer could be read from userspace to dump a lot of uninitialized kernel heap data. Update the destination buffer with the correct size of bytes copied from the user buffer.
