ASoC: msm: Fix for wma playback after SSR

After SSR apr session doesn't get destroyed as
the callback from apr driver doesn't come.Fix
this by not doing NULL allocation in q6asm callback.

ASoC: msm: qdsp6v2: clear old memhandle list when SSR happens

When SSR triggers, ASM gets RESET_EVENT callback.
Clear custom topology related old memhandle list here.
Otherwise for next ASM session opened after SSR,
old memhandle is sent to DSP and result in no audio.
Also, for ASM session while unmap during SSR, APR
command fail is expected, even then go ahead and
clear old mem handles relating to session.
Add changes to clear it from list.

ksm: Provide support to use deferred timers for scanner thread

KSM thread to scan pages is getting schedule on definite timeout.
That wakes up CPU from idle state and hence may affect the power
consumption. Provide an optional support to use deferred timer
which suites low-power use-cases.

To enable deferred timers,

mmc: core: Fix disabling of cache for Hynix cards

Commit 6932a01cd (mmc: card: quirk: disable cache for Hynix card)
claims to disable cache because of data corruption issues when cache
it is enabled. In reality, the patch allows enabling of cache during
card initialization but disallow flushing of cache during suspend or
file system sync operations. This is more dangerous than without
the commit. Move the fixups for disabling cache to mmc_fixups so as
to enable the quirk during initialization itself. Also, remove obvious
warnings everytime card is initialized during runtime resume.

ARM: Don't dump vmalloc addresses with show_data()

Memory-mapped IO address spaces cannot be safely dumped at will.
Some addresses may not be available (clocked, powered) at all times,
and may result in hangs or bus decode errors if accessed. Other
registers that are accessible may have read side-effects, and dumping
them may have adverse affects on stability or the functionality of
the affected peripheral.

Be safe, and skip dumping such addresses altogether.

ARM: Improve vmalloc address checking in show_data()

There is an unhandled corner case with the current check
which has recently been hit. The nbytes argument may be
large enough for the range being dumped to cross a
boundary between page-table mappings, and dump addresses
which are vmalloc'd in the neighboring mapping.

Check every address being dumped to see if its vmalloc'd,
not just the address passed to show_data().

sdhci: sdhci-msm: update dll configuration

The newer msm sdhci's cores use a different DLL hardware for HS400.
Update the configuration and calibration of the newer DLL block.

The HS400 DLL block used previously is CDC LP 533 and requires
programming multiple registers and waiting for configuration to
complete and then enable it. It has about 18 register writes and
two register reads.

The newer HS400 DLL block is SDC4 DLL and requires two register
writes for configuration and one register read to confirm that it
is initialized. There is an additional register write to enable
the power save mode for SDC4 DLL block.
