flush_dcache_all() operating on set/way is faster than
flush_cache() and invalidate_dcache_range() operating
on virtual address.
Tested: it saves about 12.5ms in rv1126 thunder-boot.

We misunderstood the size_src as decompressed image size.
Without this patch, the decompress can work normally, but
it wastes the time to flush data cache. Let's correct it
for thunder boot version to save boot time.

Using dm reset API to reset decompress module.
There seems to be some unknown cause to make the module
in abnormal state, which output the wrong decompress
data. Let's reset it before starting decompress.

If the decompress module doesn't access the data through dcache,
it should add flush behavior to promise getting the real data
from dram. Otherwise it may decompress the wrong data but not
report any failure.

SPL don't support IRQ and U-Boot proper is not deeply care
about boot time. There is not a mechanism to support IRQ
mode now.
In addition, the decompress irq is design to catch the exceptions
but not to decompress images continuously.

In order to prevent physical memory from being written oversize,
limit the decompressed buffer size, user can assign a size to
decompress, the reserved destination buffer size is a choice
