msm: adsprpc: Update to retrieve the physical address for ION buffer

Use follow_pfn() to obtain the physical address of ION carve

structure.

msm_serial_hs: consider flush buffer request only when DMA is in progress

TTY Core uses flush_buffer to clear out any output data before closing
port, whereas UART application can always request to do flush output data
before starting data transfer using tty supported ioctl().
receive_tty_flush is used to make decision on completion of any DMA Tx
data transfer. Using same approach when there is no DMA Tx transfer is
happening, it is breaking next DMA Tx transfer functionality. Hence
update receive_tty_flush only when there is any DMA TX transfer active.

msm: subsystem_restart: Use a CPU intensive workqueue for SSR

Using the default workqueue settings can result in the SSR
work item blocking the watchdog petting function. To avoid
this, schedule the SSR work on a workqueue that has the
WQ_CPU_INTENSIVE flag set. This will prevent any work item
posted to the workqueue from blocking other work items
posted by other drivers in the system, including the watchdog
pet work item.

analysis is possible.

msm: kgsl: Use the correct units for ADRENO_IDLE_TIMEOUT

In a few spots the ADRENO_IDLE_TIMEOUT value (measured in milliseconds)
was used directly for jiffy calculations resulting in timeouts that were
1000/HZ times longer than they should have been.  Use msecs_to_jiffies
for these situations.
