PM / devfreq: Fix out of bounds access of transition table array

The previous_freq value for a device could be an invalid frequency that
results in a error value being returned from devfreq_get_freq_level().
Check for an error value before using that to index into the transition
table.

Not doing this check will result in memory corruption when previous_freq is
not a valid frequency.

msm: pm: bug in pc debug counters logic

The logic to find the location to add debug counter
for a CPU is incorrect and due to this the counter
of next CPU is corrupted. The logic is updated to
correct this.

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.

msm: cpufreq: Fix msm_cpufreq_get_freq() for sync CPUs

When CPUs are in sync, only CPU0 has a non-NULL cpu_clk. clk_get_rate()
on other cpu_clk will return 0. msm_cpufreq_get_freq() is used in multiple
places in cpufreq framework to determine current hardware frequency.

Fix msm_cpufreq_get_freq() to return the right hardware frequency for
systems with synchronous CPUs.

msm: peripheral-loader: Change IOMAP_SIZE from SZ_4M to SZ_1M

The ioremap call made for zeroing out trailing memory is currently
requesting for a 4M memory region. This is resulting in vmalloc
allocation failures on some platforms.
Instead, request for 1M memory locations and zero out the area
in smaller chunks to make this failure less probable.
