block: Adjust cache sizes ...

Use four times more cache entries and divide the memory for each entry
by four. This lowers the linear read throughput somewhat but increases
the access speed for filesystems.

common: clock: Sample time before poller_call() ...

Change is_timeout() to sample current time before invoking poller
infrascructure to avoid occasional false timeout conditions.

Consider the following timeout loop (can be found in wait_on_timeout):

        while (!(condition)) {
	        if (is_timeout(...)) {
	       	        return -ETIMEDOUT;
                }
        }
	...

in the original logic of is_timeout() it was possible to end up in the
following situation:

        1. Immediate check of of "condition" yeilds false (not enough
           time for it to become true has passed yet)

	2. is_timeout is called which, in turn, calls poller_call()

	3. All registerd pollers take more than specified timeout time
	   to execute.

	4. Sometime during poller_call() "contition" becomes true

	5. As a result of #3 is_timeout() returns "true"

	6. Code bails out with -ETIMEDOUT early even though timeout
	   condition didn't really occur.

One concrete example of this problem was discovered on ZII RDU1
board (poller_call() is long due to a serdev) when doing large data
transfers over SPI to attached DataFlash chip.

This commit changes is_timeout() to sample the value of time before
calling poller_call(). This way first call to is_timeout() will almost
always return false thus checking the condition at least twice before
declaring a timeout.

console_simple: add newline conversion for putc_ll case ...

When console_putc uses putc_ll for early printing then it must

console: remove duplicate newline conversion ...

When the console is not yet fully initialized then console_puts falls
back to print characters using console_putc. console_putc already
does newline conversion, so do not repeat it in console_puts.

console: add missing newline conversion for putc_ll ...

putc_ll doesn't do newline conversion (and it shouldn't do, as it's
a static inline function for early debugging, adding more code there
is not nice), so add newline conversion to the console code when
it uses putc_ll for printing early messages.

bootm: Split bootm_load_devicetree into two functions ...

It is not always desired to get the devicetree from image data and load
it to a SDRAM region at the same time. Sometimes it's enough to just
load it to an allocated address (in case the user has no constraints
where the devicetree should be placed.

This patch splits bootm_load_devicetree into bootm_get_devicetree which
returns a pointer to the allocated devicetree and bootm_load_devicetree
which loads the devicetree to a specified region.
