OMAPDSS: DISPC: more precise scale limits checking

Use division with rounding-up when checking if maximum downscale ratio
was reached. This allows to avoid SYNC_LOST errors in case when small
amount of extra pixels or lines (usually 1-3) not taken into account
OMAPDSS: DISPC: fix pclk divisor limits

According to TRM, minimal pixel clock divisor value can be 1.
Fix corresponding checks, as high resolution panels use undivided
pixel clock frequency.

Also certain scaler unit constraint must be met: in case DISPC_CLK
and pixel clock frequencies are equal, set IPC to work on rising edge.

[ARM] omap: try not to allocate memory page by page

Instead, try to allocate memory for all physical pages together.  Idea from
Lakshman Gowda <lakshman79@ti.com>.  Speeds up allocations from the
tiler carveout by ~50ms.

This patch also combines three kzallocs into one.

PM / Hibernate: Correct additional pages number calculation

The struct bm_block is allocated by chain_alloc(),
so it'd better counting it in LINKED_PAGE_DATA_SIZE.

panic: don't print redundant backtraces on oops

When an oops causes a panic and panic prints another backtrace it's pretty
common to have the original oops data be scrolled away on a 80x50 screen.

The second backtrace is quite redundant and not needed anyways.

So don't print the panic backtrace when oops_in_progress is true.

PM / Hibernate: Drop the check of swap space size for compressed image

For compressed image, the space required is not known until
we finish compressing and writing all pages.
This patch drops the check, and if swap space is not enough
finally, system can still restore to normal after writing
swap fails for compressed images.
