ion: invalidate buffers before zero'ing

Currently, we invalidate the cache for buffers being zero'd *after* we
zero them. However, this is racey since a dirty cache line from an
earlier mapping could be written out to memory between the zero'ing and
the invalidation. Fix this by invalidating the cache *before* zero'ing
the buffer.

Before this change, I was seeing corruption with:

    $ cat <<EOF | ./memory_prof -e -i -
    simple_alloc,1,ION_SYSTEM_HEAP_ID,ION_FLAG_CACHED,0x100000,1MB
    simple_basic_sanity,1
    simple_profile,1
    simple_free,1
    EOF

After this change, no corruption.

mmc: core: add deferred resume support

This patch enables the deferred resume support which would
prevent initialization of the card each time the system resumes.
With this change, the resume process would only be initiated if
a request is received.

Following scenario can occur:
1. device runtime suspended, system suspend is triggered
   When resumed, the device would not be resumed until a
   request is received.
2. device is runtime active, system suspend is triggered
   When resumed, the device would be marked as BUS_NEEDS_RESUME
   and actual resume would happen, when a request is received.
   At this point, the device may also enter runtime-suspend or
   system suspend may also occur. In both the cases, since the
   device has not been resumed, it won't be suspended again.
   However, the platform device would be runtime suspended
   and resumed as before.
   It can so happen that the card is removed even before a
   request is received. In this case the device would be
   resumed and card would be removed from core layer and
   upper layers would be notified.
In case of SDIO cards, this change would not have any effect
since manual resume would be enabled for devices supporting
a block read/write commands.
