rimps_memlat driver will cache PMU counter values when cpu
is going down in hotplug path and also when CPU is entering
lpm. Once the PMU counter values are saved to the shared memory,
cache valid bit is set, and it is cleared when cpu comes back online
or exit from lpm.
RIMPS expects the PMU cache flag to be valid, when cpu is offline
or entered lpm. Observed a race when the hotplug is in progress
and that particular cpu can enter and exit lpm. The current
implementation clears the cache flag during lpm exit without
checking the cpu hotplug status. Once hotplug is complete, core
goes offline and the status flag will remain in incorrect state
indicating cache area is invalid, which will cause RIMPS to read
PMU counter values directly from hardware which will result in APB
read errors.
When hotplug is in progress, do not set status flag to
PMU_CACHE_INVALID in CPU_PM_EXIT path.

Setup pmu counter functions of rimps memlat driver check cpu_is_hp
flag before creating counters, and the setup of pmu counters will
be called in two places one in probe and other when cpu is coming
up from hotplug path.
The hotplug path will clear cpu_is_hp after the pmu setup calls are
issued, but pmu setup function will not create pmu events as the
cpu_is_hp flag not cleared at this point, this results in pmu
counters not getting setup even cpu is up from the hotplug path.
Add a parameter to these functions indicating from which path these
are called and update the logic accordingly to allow creation of
pmu events when core is coming up.

RIMPS memlat driver reads the current PMU counter value
using perf_event_read_local() API at the time of core
going offline or entering LPM and saves the current
snapshot to a shared memory for access by RIMPS.
RIMPS reads these values from the shared memory when
core is offline or in LPM state, and reads directly
from PMU hardware when core is online. The value read
from hardware and the one read from shared memory are
going out of sync because perf event driver limits the
counting range of PMU counter to half of the total range
supported by hardware, and it configures the counter to
start counting from midpoint at the time of counter reset
and upon overflow. It keeps adding the delta read from
hardware counters to software maintained counters and it
returns the same through perf_event_read API.
As this is not the exact same value as what is read from
hardware counters, the values read by RIMPS from shared
memory are going out of sync.
To address this get the current snapshot of hardware counter
value from prev_count member of hw_perf_event structure which
is part of perf_event structure, and store that to shared memory.

Currently ipc_logging will capture the usb request's dma address but
when sg list is used usb request's dma address is not populated. This
change adds start_sg's dma address which is populated when sg list is
used for usb transfers. Also increase the number of log pages to capture
more ep events.

This saves an extra fops on each iteration for game on and off.
