[why]
Surface height/width for Chroma has another variable that it should be
intialized to, chroma_size. Fixing this will help pass DML2.0 validation
for YCbCr420 tests, DCHB006.109,129, DCHB014.011,012.
[how]
Assign SurfaceHeight/WidthC to chroma_size.height/width

Some drivers use one event callback for multiple widgets but still need
to perform a bit different actions based on actual widget. This is done
by comparing widget name, however drivers tend to miss possible name
prefix. Add a helper to solve common mistakes.

Commit 45201c879469 ("powerpc/nohash: Remove hash related code from
nohash headers.") replaced:
if ((pte_val(*ptep) & (_PAGE_ACCESSED | _PAGE_HASHPTE)) == 0)

On 8xx, PAGE_NONE is handled by setting _PAGE_NA instead of clearing
_PAGE_USER.
But then pte_user() returns 1 also for PAGE_NONE.
As _PAGE_NA prevent reads, add a specific version of pte_read()
that returns 0 when _PAGE_NA is set instead of always returning 1.

In this code "ret" is type long and "src_objlen" is unsigned int. The
problem is that on 32bit systems, when we do the comparison signed longs
are type promoted to unsigned int. So negative error codes from
do_splice_direct() are treated as success instead of failure.
